Cisco Wireless Phones Update

August 11th, 2013

August 10th 2013     OK we have made some big changes and major steps towards resolving one of the most significant issues since my start in 2011,  our wireless phones in the health care facility.   The problem had been pervasive from day 1 but nobody ever made a serious effort to address the root cause.    I talked to several vendors, some wanted to overhaul our wireless infrastructure completely and I was even looking at Meraki as a possible solution.     The Meraki solution, turns out it would have been a disaster as the cloud based controller is notorious for lag, jitter and dropped packets which these 7921 and 7925 cisco units have no tolerance for.   Not a slap at Meraki, even though they now are Cisco.  Meraki works wonders for standard PC type clients.  I actually have a few meraki units in some of my Residence floors and they love it.     We finally went with a vendor/partner that said what we have is completely workable with a few minor adjustments.    Cost for the overhaul about 25k  cost for the winners proposal about 5k  da…

I worked closely with them and acted as the interface with the Nurse staff who are the front line users of these phones and were at first reluctant to invest the time and energy

For starters, we realized there was a lot of traffic and contention in the wireless network.  However, all of this was in the 2.4Ghz band.    We switched the cisco phones to the 5Ghz band.    We needed to replace about 10 1120 APs with some 1240 units that supported 5Ghz and we needed to add 5Ghz antennas as well.   Wow, huge improvement.  Complaints and issues were immediately down by about 65%.   Our work was not yet done however as many of the APs could not see each other and some controller settings needed to be changed.   Stay tuned for more…

Cisco Commands for Reference

December 2nd, 2012

Compliments to http://www.thenetworkadministrator.com/ciscoroutertips.htm

Top 10 Commands show version: Start simple;

show version:    this command gives uptime, info about your software and hardware and a few other details.

show ip interface brief: This command is great for showing up/down status of your IP interfaces, as well as what the IP address is of each interface. It’s mostly useful for displaying critical info about a lot of interfaces on one easy to read page.

show interface: This is the more popular version of the command that shows detailed output of each interface. You’ll usually want to specify a single interface or you’ll have to hit ‘page down’ a lot. This command is useful because it shows traffic counters and also detailed info about duplex and other link-specific goodies.

show ip interface: This often overlooked command is great for all the configuration options that are set. These include the switching mode, ACLs, header compression, ICMP redirection, accounting, NAT, policy routing, security level, etc. Basically, this command tells you how the interface is behaving.

show ip route: This indispensable command shows your routing table, which is usually the primary purpose of the box. Get to know the options on this command.

show arp: Can’t ping a neighbor? Make sure you’re getting an arp entry.

show running-config: This is an easy one. It tells you how the box is configured right now. Also,

show startup-config” will tell you how the router will be configured after the next reboot. show port: Similar to the show interface command on routers, this command gives you the status of ports on a switch.

show vlan: With the trend toward having lots of VLANs, check this command to make sure your ports are in the VLANs you think they are. Its output is very well designed.

show tech-support: This command is great for collecting a lot of info. It basically runs a whole bunch of other show commands, and spits out dozens of pages of detailed output, designed to be sent to technical support. But, it’s also useful for other purposes.


Another Big one

show cdp neighbor    to see how the switches are connected


Now on to some live Troubleshooting a Vlan and Wireless issue

Cisco Updates

November 4th, 2012

Blog to post updates for our Cisco world to include CUCMBE, WLC4404, Catalyst 3560 and more…

Our Wireless Environment is a Campus style without about 85 Access Points controlled by a Cisco WLC 4404-100.    It is about time to start phasing out our aging 1121 and 1241 Access Points.  Our WLC is getting close to end of life also.  Our Cisco Partners suggest we buy another WLC /Flex for about $30K and phase in with new 3501 and  3602 at about $900 each.      I am taking a serious look at Meraki and have been testing as a Proof of Concept.  My main concern was that it would not work with our Cisco Wireless 7921 and 7925 IP phones.   Meraki supports VLan taging though and that made it a non issue.   Also, they support a NAT mode where Clients receive IP addresses in an isolated network.     My only issue thus far has been getting the Vlan to send internal clients in our data network to find my windows dhcp.  Watching the traffic with wirehark and Cisco sniffers shows us that the Vlan tagging works but once it hits the cisco box it is untagged likely expecting the DHCP to be in broadcast, it then reverts to a mDNS and still doesnt find the Windows DHCP which is a separate IP space.    My only thought now is a DHCP Relay agent or an IP helper-address be setup in the cisco switches…  Anyhow I want the Meraki solution to work because I dont need to spend $25-30K on a controller…


So now that Cisco bought Meraki can that be seen as good or bad?

OK now it looks like we have too many APs creating too much traffic/chatter and forcing some to lower their TX power  hmm… We are going to do an RF scan  to see exactly what we have.  I dont think they put any plaaning in play before they deployed these many years ago

Mar 9,  We have decided to commit to a full RF site survey of all buildings and floors.  We will follow the procedures in following Doc from Cisco  http://www.cisco.com/en/US/docs/wireless/technology/vowlan/troubleshooting/8_Site_Survey_RF_Design_Valid.pdf

We will have a partner involved wha has performed many of these in mission critical Health Care Facilites.




Windows 7 and Offline Files

 Configuring New Offline Files Features for Windows 7 Computers Step-by-Step Guide

Published: April 21, 2010

Applies To: Windows 7, Windows Server 2008 R2

Offline Files (also known as Client Side Caching or CSC) makes network files available to an end user when a network connection to the server is unavailable or slow. When working online, file access performance is at the speed of the network and server. When the server is unavailable or the network connection is slower than a configurable threshold, files are retrieved from the Offline Files folder at local access speeds. Offline Files is useful for the following administrators and end users:

  • Administrators that want to centralize data from client computers for administrative tasks such as backup.
  • Network administrators that want to optimize bandwidth usage and enhance the experience of users in branch offices who access files and folders that are hosted by corporate servers located offsite.
  • Users that want to continue to access network files if there is a network outage.
  • Mobile users that need to access network files while working offline or over slow networks.

About this guide

The purpose of this guide is to help administrators become familiar with new Offline Files features and associated Group Policy settings in Windows 7 and Windows Server 2008 R2. This guide provides an overview of the new functionality, an overview of deploying Folder Redirection, and step-by-step procedures for configuring the new settings. Administrators can configure Offline Files by using Group Policy for multiple users when users’ folders have been redirected to a share by using Folder Redirection. We recommend deploying Folder Redirection in a lab environment before deploying it in a production environment.

Technology review

The major changes to Offline Files for Windows 7 and Windows Server 2008 R2 include significantly improved wide area network (WAN) file access and an improved network file experience for remote users. New functionality for Offline Files includes the following:

  • Fast first logon
  • Usually Offline support with Background Sync
  • Exclusion list
  • Transparent Caching

Fast first logon

Fast first logon is a new feature that frees users from waiting while files are copied to the server the first time they log on after a Folder Redirection policy setting has been applied that redirects the path of a user folder to a network location. It also optimizes network usage on WAN links by synchronizing files as a background task. Prior to Windows 7, after a policy setting was applied that redirected a user’s folder to a network location, the user had to wait while the contents of the folder were moved to the new location. This process could take a considerable amount of time if there was a large amount of data to move and the network was slow. On Windows 7, as long as Offline Files is enabled (it is on by default), the user must wait only for Windows to move the files into the local Offline Files cache. After the files are moved, the user logs on and is free to perform other tasks while Windows synchronizes the locally cached data over the network as a background task.

Usually Offline support with Background Sync

Usually Offline support provides remote and branch office users with faster access to files that are located in a network folder across a slow network connection. Windows 7 enhances this feature by including Background Sync, a feature that synchronizes Offline Files in the background, ensuring that the server is frequently updated with the latest changes. When a client computer’s network connection to a server is slow (as configured by the administrator), Offline Files automatically transitions the client computer into an “Offline (slow connection)” mode. The user then works from the local Offline Files cache. On Windows 7, Background Sync runs at regular intervals as a background task to automatically synchronize and reconcile changes between the client computer and the server. IT administrators can configure synchronization intervals and block out times. With this feature, users no longer must worry about manually synchronizing their data with the server when working offline.

Exclusion list

The exclusion list feature reduces synchronization overhead and disk space usage on the server, and speeds up backup and restore operations by excluding files of certain types from replication across all Folder Redirection clients. Prior to Windows 7, all files in an Offline Files folder were replicated to the server. This often meant that a user’s personal files or large files not relevant to the enterprise were replicated to one or more servers, thereby consuming disk space and slowing backup and restore times. On Windows 7, administrators can use the Offline Files exclusion list feature to prevent files of certain types (for example, MP3 files) from being synchronized. The list of file types is configured by the IT administrator by using Group Policy.

Transparent Caching

Transparent Caching optimizes bandwidth consumption on WAN links and provides near local read response times for mobile users and branch office workers that are accessing network files and folders that are not explicitly made available offline. The greatest benefits of Transparent Caching are realized when BranchCache is deployed. BranchCache is designed to reduce WAN link utilization and improve application responsiveness for branch office workers who access content from servers in remote locations.

Prior to Windows 7, to open a file across a slow network, client computers always retrieved the file from the server, even if the client computer had recently read the file. With Windows 7 Transparent Caching, the first time a user opens a file in a shared folder, Windows 7 reads the file from the server and then stores it in the Offline Files cache on the local hard disk drive. The subsequent times that a user opens the same file, Windows 7 retrieves the cached file from the hard disk drive instead of reading it from the server. To provide data integrity, Windows 7 always contacts the server to ensure that the cached copy is up to date. The cache is never accessed if the server is unavailable, and updates to the file are always written directly to the server.

Transparent Caching is not enabled by default. IT administrators can use a Group Policy setting to enable Transparent Caching, improve the efficiency of the cache, and configure the amount of hard disk drive space that the cache uses.

Scenario overview

This scenario presents the procedures an administrator can use to configure Offline Files settings for Windows 7 client computers by using Group Policy on a Windows Server 2008 R2 computer configured as a domain controller. Administrators can configure Offline Files for Group Policy objects (GPOs) when folders on client computers have been redirected to a share by using Folder Redirection.

The scenario shows you how to configure the settings by using the Group Policy Management Editor. It also provides an overview of deploying Folder Redirection. Offline Files is particularly useful when folders on multiple computers are redirected to a share by using Folder Redirection. When you configure Offline Files by using Folder Redirection, the redirected files are cached on client computers so that they are available for offline use.

This guide presents step-by-step procedures for configuring the following Offline Files features:

Configure Background Sync and enable Transparent Caching when you have one or more of the following environments:

  • Mobile users are connected to a remote server over slow, unreliable networks.
  • Branch office users are connected to the server in the headquarters over high latency, low bandwidth networks, and BranchCache is not deployed.
When BranchCache is deployed, transparent caching is automatically enabled.

You can configure the policy setting “Exclude files from being cached” when you need to keep files of certain types on client computers from being replicated to the server.

Considerations for configuring Offline Files

Before configuring Group Policy settings for Offline Files, consider the following:

  • The Offline Files feature is enabled by default on the following client computer operating systems: Windows 7 Professional, Windows 7 Enterprise, Windows 7 Ultimate, and Windows Vista.
  • This feature is turned off by default on Windows Server operating systems. To enable Offline Files on Windows Server 2008 and Windows Server 2008 R2, you need to first install and enable the Desktop Experience feature by using Server Manager, and then enable Offline Files in Sync Center.
  • You can configure Background Sync, Transparent Caching, and file exclusion only on Windows 7 and Windows Server 2008 R2 computers.

Upgrading a computer over a slow link

When upgrading a computer from, for example, Windows Vista to Windows 7, the entire Offline Files cache is not migrated to the new operating system. Only the content in the cache that hasn’t been synchronized with the server is migrated. After Windows 7 is installed, files on the server are synchronized with the cache.

The entire cache is not migrated because it can potentially impact performance and disk space. The Windows 7 client computer needs to have enough disk space to accommodate both the new operating system and the Offline Files cache. When the client computer is connected to the server over a slow network, we recommend that you migrate the entire cache. The time to synchronize the entire set of network files from the server to the client depends on the latency and bandwidth of the network as well as the size of the file set. Use the following registry key to migrate the entire Offline Files cache and set the value of the registry key to 1:

HKLM\System\CurrentControlSet\Services\CSC\Parameters DWORD MigrationParameters = 1

This setting is not preserved, so you need to reset it each time you upgrade the computer.

Configuring the Offline Directory Rename and Delete registry setting

In Windows 7 the ability to delete or rename folders that were cached by offline folders when working in the offline mode is enabled by default. Because renaming a folder is treated like a delete and a subsequent create of the same directory structure, you may need to update the list of directory paths that the functionality can be enabled for.

The registry setting to update these paths is:


The recommended way to update this setting by using the command line is to specify the value, data, and type when adding a new key. For example,

REG ADD “keyname” /v \\server\share /t REG_DWORD /d 1

Deploying Folder Redirection

Folder Redirection enables an administrator to redirect the location of specific folders within user profiles to a new location, such as a shared network location. Folder Redirection provides users with a centralized view of select user profile folders from any domain-joined computer. Users then have the ability to work with documents located on a server as if they were located on the local drive. For example, it is possible to redirect the Documents folder, which is usually stored on the computer’s local hard disk drive, to a network location.

When deploying the Folder Redirection Group Policy setting for specific folders, those folders are also automatically cached by default on the client computer by using the Offline Files technology. This allows users to seamlessly access files from the cache when no network or a slow network is present, with the ability to synchronize the changes between the client and the server in the background.

Using Offline Files with Folder Redirection and Group Policy gives administrators centralized control of user configurations and data management. It provides the most flexibility when configuring and managing various types of users and a convenient way to manage user data (such as backup and restore) from a central location.

In a domain environment, use the Group Policy Management Console (GPMC) on a domain controller to redirect specific user profile folders, as well as to edit Folder Redirection policy settings. On a Windows Server 2008 R2 computer, in Server Manager, click Add Features to install Group Policy Management.

Folder Redirection is located under Windows Settings in the console tree when you edit domain-based Group Policy. The path is [Group Policy Object Name]\User Configuration\Policies\Windows Settings\Folder Redirection. Use the Group Policy Management Editor to configure Folder Redirection for a domain (everyone) or groups of users from a domain controller:

  1. In the GPMC tree, right-click the Group Policy object (GPO) that is linked to the site, domain, or organizational unit that contains the users whose user profile folders you want to redirect, and then click Edit.
  2. Expand User Configuration\Policies\Windows Settings\Folder Redirection and then select the specific folder to be redirected, such as Documents.
  3. To configure folder settings, right-click the folder to be redirected, and then click Properties.


For an overview of Folder Redirection and step-by-step procedures for configuring Folder Redirection from a Windows Server 2008 R2 computer, see Using Folder Redirection (http://go.microsoft.com/fwlink/?LinkId=188721).

Configuring Offline Files settings for Windows 7 computers

There are several Group Policy settings for Offline Files that you can configure for multiple users in a domain environment. This guide explains the configuration options for the new settings introduced in Windows 7.

The following table shows the three new Group Policy settings for Offline Files. All settings are located under Computer Configuration\Administrative Templates\Network\Offline Files.

Group Policy Settings


Setting name Default value
Configure Background Sync Enabled
Exclude files from being cached Disabled
Enable Transparent Caching Disabled

In this scenario, the administrator is applying the Offline Files settings to the domain. To apply Group Policy settings to the entire domain, create a new GPO, link it to the domain, and edit the settings in that GPO.

To configure Offline Files settings by using Group Policy

  1. In the GPMC tree, right-click the Group Policy object (GPO) for which you want to configure the Offline Files settings, and then click Edit.
  2. Under Computer Configuration, expand Administrative Templates\Network\Offline Files.
  3. Configure settings as needed.

Configuring Background Sync

Background Sync is a machine-specific setting which applies to any user who logs on to the specified computer while this policy setting is in effect. This policy setting is in effect when a network folder is determined to be in “slow-link” mode, as specified by the “Configure slow-link mode” policy setting.

For network folders in “slow-link” mode, a sync will be initiated in the background on a regular basis according to these settings, to synchronize the files in those shares/folders between the client and the server. By default, network folders in “slow-link” mode will be synchronized with the server every 360 minutes, with the start of the sync varying between 0 and 60 minutes.

You can override the default sync interval and variance by setting ‘Sync Interval’ and ‘Sync Variance’ values. You can also set a period of time where background sync is disabled by setting ‘Blockout Start Time’ and ‘Blockout Duration.’ To ensure that all the network folders on the computer are synchronized with the server on a regular basis, you may also set the ‘Maximum Allowed Time Without A Sync.’

You may also configure Background Sync for network shares that are in user-selected “Work Offline” mode. This mode is in effect when a user selects the “Work Offline” button for a specific share. When selected, all configured settings will apply to shares in the user-selected “Work Offline” mode as well.

To configure Background Sync

  1. In the Group Policy Management Editor, click the Offline Files folder.
  2. In the right pane, double-click Configure Background Sync.
  3. Click Enabled, and under Options, make selections as needed.
  4. Click OK.

Enabling Transparent Caching

Enabling this policy setting optimizes subsequent reads to network files by a user or an application. This is done by caching reads to remote files over a slow network in the Offline Files cache. Subsequent reads to the same file are then satisfied from the client after verifying the integrity of the cached copy. This policy setting not only yields improved end-user response times but also decreased bandwidth consumption over the WAN links to the server.

The cached files are temporary and are not available to the user when offline. The cached files are not kept in sync with the version on the server, and the most current version from the server is always available for subsequent reads.

To enable Transparent Caching

  1. In the Group Policy Management Editor, click the Offline Files folder.
  2. In the right pane, double-click Enable Transparent Caching.
  3. Click Enabled, and under Options, enter a network latency value.
  4. Click OK.

Excluding files from being cached

Use this setting to exclude certain file types from being made available offline. You need to specify the file extensions of the file types that should be excluded. A user will then be unable to create a file of this type in the folders that have been made available offline.

To exclude files from being cached

  1. In the Group Policy Management Editor, click the Offline Files folder.
  2. In the right pane, double-click Exclude files from being cached.
  3. Click Enabled, and under Options, enter the file extensions that you want to exclude from being made available offline.
  4. Click OK.

Slow Link Config


No delete for sync partnership

I’m running Vista Ultimate and wish to remove a sync partnership with
a network share. When I open up the Sync Center and click the
partnership, there isn’t a delete option. Any idea how I can remove
this? Please, it’s driving me crazy.

Me too, i’m having exactly the same problem.
Disconnecting does not do anything…. once you reconnect the drive it shows
all the syncs again…. this is such a pain in the ass, and nearly crashed
my hard drive

prob I cant delete the disconnected share… so its forever in my sync folder..
delete is greyed out….
Id either have to connect back to the shared, or find it hidden somewhere on my local drive…

I gaveup and disabled the whole Offiline service…
Offline is a sloppy unreliable mess….
what a dumb concept.. copy/ pasting is easier and safer..
and ot dpesnt kill system resource like offline does..

also if you run sysinternals procmon (free & no install needed)… you will see a a million processes relating to offline files… BIG MESS

Re: No delete for sync partnership

If I’m understanding correctly, try this…

In Windows Explorer or “Computer” select Explore and right click on mapped
network drive and select “disconnect”.
That should delete your sync partnership I believe. I hope I understood
your problem correctly.

Seems like this would work — after all the “check-mark” is the universal computer symbol for “click me again to turn me off/revers this action” — apparently though, microsoft missed that meeting, or more likely they did a half ass job on the operating system — because they were to focused on preventing piracy. Which would be ironic considering it was cracked and pirated the same month it came out.

Sure vista has a FEW neat features — but all in all — this is what I would have expected in 2003-2004. XP camp out in 2001 — In the 6 years from 95-2001 we saw Win95/Win98/Win2K/WinMe/WinXP — so 5 versions going from 95 to XP. Then in the next 6 years — we go from XP to vista?!?!? Half the cool features can be done with third party software on XP, and have been included in Mac and Linux operating systems for about a year or two prior to Vista.

I was really hoping that the fact microsoft was taking thier sweet freakin time with vista, would mean that they would actually have thought stuff through. How foolish of me to ever have ANY faith whatsoever in microsoft’s ability to make anything good! (aside from keyboards — they make pretty good keyboards — that about the ONLY positive thing I can say about them)

Sorry for that rant — I had to vent a little….

Anyway – back to the point at hand — when you try to “uncheck” the “always availaible offline” — NOTHING happens — it just stays checked. BRILLIANT MICROSOFT!!!!

And from the looks of things so far — I think we all might just be stuck, until they release a patch to fix the problem, or someone strolls along and tells us the backdoor way.

I was also looking for an answer to this problem.

I think I have the answer.

It appears you can not remove a sync partnership until you have
resolved all discrepencies.

If you select each descrepency and resolve it by either deleting the
local or remote copy you can then select the share and delselect the
sync option.

It appears that it has been a while since someone posted to this thread. After doing a Google search, I stumbled across this forum thread. I want to thank all the contributors of this thread as all suggestions have helped me more than words can describe. I have a few other things to add as well as to describe the result of following all the provided suggestions.

Steven Bland’s method of removing offline files works well if you need to remove specific Offline Files from the Sync Partnership list. In the event that you want to remove ALL files/sync partnerships, disable Offline Files, and then click on the “Disk Usage” tab and click the button labeled “Delete Temporary Files”. This will automatically remove all Offline Files for you. You can re-enable Offline Files if you desire and re-establish any desired sync partnerships.

I found the answer to this problem. In Sync Center on the left select the link for “Manage offline files”. The next screen will give the option of stop syncronizing. Rebooting is required for this to take effect. After the reboot, the sync partnership is no longer active.

I tried Sync Center once, then tried to remove with no luck. After no reply from MS support (no surprise), I poked around and found a way to disable.

In control panels, select Offline Files. Here you are able to delete and clean up temporary local files and disable the offline files feature. After a restart, there are no “partnerships” and no systray application running.

You need to do it manually.
Go to C:\Windows\CSC\v2.0.6\namespace

and then delete the server or folder that you want to remove from you partnership, and reboot.

It’s possible that you have to take ownership of certain folder.

Ex: to take ownership of the folder CSC

– right click the CSC folder, chick properties.
– click security
– advanced
– owner
– edit
– select or add your username to the list
– put a check mark in “REplace owner on …”
– OK

Do this for the folder that you are not allowed to see.,,,

I did this and was able to delete the offline files I didn’t want but subsequently I think something is messed up now. I can’t seem to be able to add new share to “Make Available Offline”, as well “Offlinecreate new , but I think I have messed out Offline File “Disk Usage” is off. It just sees 99GB. I assume I need to set things back to the original permissions. Do you know what that maybe?

I experienced the same symptoms as described in this thread:
unability to remove a sync partnership

Followed suggestion from jotr25 to remove the sync folder from c:\windows\CSC\v2.0.6\namespace

It worked: sync partnership was no longer there but at this point i had the same problem smoothmoosehad: Offline folders no longer worked.

I got it to work again by restoring the permissions on folder c:\windows\CSC to its original settings: simply by following the same prodedure as cited by jotr25 but then removing myself from the permission entries list and making sure the checkbox include inheritable permissions from this object’s parent was checked. In this way the folder regained it’s original security settings and after a reboot offline folders worked again

Start -> Offline Files -> View your offline files -> select the folder, hit delete

I think this is a case of really bad UI design. They should have given access to this function in Sync Center.

Believe it or not, many devs will tell you that Vista is the first time in Windows that the internals are better than the presentation. (Most people, not even most “IT experts” know this to be true…)

edit: okay, that didn’t work. The Vista Help isn’t very helpful either:



Some sync partnerships may not offer an option to delete the partnership. If they don’t have this option, try opening the program or location where you set up the sync partnership to see if you can turn it off or delete it using that program or location.

What they mean by “try” is totally beyond me.

The Sync center team blog is absolutely useless as well: http://blogs.msdn.com/synccenter/arc…commentmessage

Two posts in two years. Great. Not answering a single question from their customers. I’m beginning to wonder if they got fired or something for this blunder.

A dead sync target with Offline folders

Following jotr25 post related to CSC folder, I could see that this is where
the offline content is stored. However, I thought there has to be an easier

This worked for me:
1 – Control Panal -> Offline Files -> “Disable Offline Files”
2 – Click the “View your offline files.” (rather than opening CSC folder
mentioned above.)
3 – Delete folders you no longer sync
4 – Go back to the Offline Files window and click OK
5 – Restart computer
6 – Control Panal -> Offline Files -> “Enable Offline Files”

I will post again if I find a shorter method.

Re: No delete for sync partnership

I just searched for solutions to this problem, and I wanted to share my experience with this problem, and the solution I found.

I had a problem with a sync partnership in windows 7 against a sql server 2000 that was installed together with a program installed a while ago. The program was uninstalled, but the sync partnership was still there. I searched in the registry and in the file system for pieces of the sync partnership, but nothing found.

I disabled offline files, found out that sql server file folder was still resideing under program files, tried to delete files, but ended up with 2 dll-files that failed being deleted, because they were in use in sync center.

I used cmd as admin, and unregistered the dll-files with regsvr32 /u nameofdllfile.dll for the both files, one was uninstalled, the other failed. I rebooted, and no sync partnership was showing in sync center, I was also able to delete the whole sql folder in program files.

This solved my problem. Hope this can help others with the same problem.

Re: No delete for sync partnership

I don’t even understand what this sync feature is and I’m an engineer. It just popped up yesterday and I want to get rid of it. I want it out of the tray. I set it for hidden and rebooted and it was invisible, but now the icon is back.
Why would it try to sync my 16 gig ready boost flash drive? I have a little 4 gig stick I always keep plugged into my hub and it tried to sync it to something too. It didn’t try to sync my 320 gig mini HD that is always plugged into the powered hub.
I have an H-P Notebook (another nightmare) running Vista Home Prem 64 bit.
I chased it down to it’s origin with a computer search utility I have but I was only able to delete half of it. Perhaps I’ll run it down again and take ownership then see if I can delete the remainder of it.
I don’t even see it in msconfig or I’d just turn it off like other junk on this machine. I’m tired of having to perform restores and recoveries so I just turn them off if my expansive collection of utilities can’t remove or destroy them. I have utilities that nearly remove the solder from the board but they dig so deep that they often cause other problems.
Incidentally, you guys are hilarious to read, you sound like I do when I’m pissed about the stupidity and/or negligence of companies and incompetent engineers. I personally like Vista because you can get your hands greasy with it unlike 7 which I had and sold. It was too consumer oriented. But design and build the OS and programs right before you market it, H-P, Microsoft, et al.

And OpLocks…

  • EnableOplocks REG_DWORD 0 or 1
    Default: 1 (true)
    Specifies whether the server allows clients to use oplocks on files. Oplocks
    are a significant performance enhancement, but have the potential to cause
    lost cached data on some networks, particularly wide-area networks.

    By default, the registry entry is 1 (oplock enabled), as a rule of thumb you
    should set this key to 0 (disable oplock) when sharing files with
    Xbase++/Clipper/FoxPro and MS-Access. We have not encountered any
    performance drawbacks in real-world scenarios after having disabled oplocks.
    However problems with Xbase++ file-based database applications simple went
    away after re-configuration of the server.




Compound TCP in high bandwidth environements

November 27th, 2010

We are studying methods to improve bandwidth for large file tranfers over hight bandwidth networks.    In our test environment we have a windows 2008 r2 server with the following tcp interface config

set global rss=enabled chimney=automatic autotuninglevel=normal congestionprovid
er=ctcp ecncapability=disabled timestamps=disabled netdma=disabled dca=disabled

and a windows 7 config
set global rss=enabled chimney=enabled autotuninglevel=normal congestionprovider
=none ecncapability=disabled timestamps=disabled netdma=disabled dca=disabled

We will first test with thsese default settings and post results.  We will next enable CTCP and note the results.   IPerf will be used to tst.    The reported bandwidth between endpoints is 500Mbps.   Let thge iperf testing begin.  Results will be posted. 


Going Virtual

February 2nd, 2010

We are excited about the latest free offerings in Windows 7 (Ultimate + ) to support workstations booting from a Virtual Hard Disk(VHD). Using a Master VHD, you can add multiple differencing VHDs which are much smaller and portable children of the master clone. You can move them around and if one gets hosed, you just recreate another clone from the parent. We are rolling out a small office test environment with this setup.      More to follow…

Windows Server 2008 + Windows 7 Client = Benefits?

October 12th, 2009

I have a small office where they are looking at the cost / benefit of upgrading their SBS Windows 2003 servers and XP clients- also an old exchange server but thats an done deal.

We will study the benefits/payback of a pure Server 2008/ Client win 7 environment. 

We always welcome pertinent comments
