Offline Files and Synchronization Settings

Posted on 2006-04-20

I recently moved my OF data to another server and want to delete the Synchronization entry for the old server. Anybody know how to do that?

Thanks for any feedback.

    Wow! What a mess.  I found three threads of unhappy Offline Files users with that same problem, and none of them seemed to ever solve it.  
    I have posted excerpts below.  They seem to be all giving up on Offline Files from this problem.

    One thing to try is from the windows resource kit -- a tool called csccmd.exe.  

    To obtain the CSCCMD tool, contact Microsoft Product Support Services. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:;[LN];CNTACTMS

    I got that from here:

    Another idea that occurs to me is to set up another server on the network with the same name as the old server temporarily just to make the synchronization work, and then right-click those files to make them no longer available offline.

    Another suggested fix is a "Hard Reset" as explained here:;en-us;230738

    Anyway, here is what I found on the threads:

    Here is problem a man named Robert Lewis had:

    "Case in point:
    \\oldserver crashed recently. Fortunately, we had capacity on \\newserver, so I restored our data from \\oldserver\data to \\newserver\data. Now, no matter what I do in Windows Explorer\Tools\Synchronize... Synchronization fails with the message that \\oldserver\data is unavailable. It does not help to remove references to \\oldserver in CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\NetCache\Shares or HKEY_USERS\...\Software\Microsoft\Windows\CurrentVersion\NetCache\Shares

    This is the first link that has given me any hope of cleaning up my CSC configs. Any ideas?"

    Here is the recommended fix:

    "You can either rename that server share in the cache by using the csccmd utility's moveshare option, or delete your local copy of files from that server by using the "Delete Files" button on the Offline Files tab."

    Here is another recommended fix with more details:

    "I had the same problem you had; on the windows resource kit there is a tool called csccmd.exe that you can use:

    csccmd.exe /MOVESHARE:\\oldserver\share \\newserver\share
    csccmd.exe /RESID

    that should fix the problem"

    But that did not work -- see here:

    "I tried the csccmd.exe and that exact command...I didn't try the resid switch though.

    I just got off the phone with Microsoft and got the latest version of csccmd and was also on the phone with them for about 4-5 hours and had them stumped.

    I tried just about everything and the MS Engineer also tried what I tried and a few others and still no luck.

    Not sure what the issue is... "

    Here is the long thread I got all that from:

    Here's a guy with the same problem.

    The suggested fix was: "Clear the IE cache. (IE, tools, Options, Delete Files button, include offline content.)"

    Here is another person with the same problem.

    The suggested fix was "to kill sync to dead server you need to re-initialize cache by holding down ctrl+shift when hitting the delete files button. this will re-initialize all offline files and you can then go back and make new folders available for offline use"

    Deleting Files and Folders

    You can use two methods to safely remove offline files from the cache without affecting network files or folders. You can delete selected files from the Offline Files folder, or you can delete all files associated with a particular network share by using the Delete Files feature from the Offline Files property page. Do not directly delete or move any files from the systemroot\CSC folder.

    Deleting Files from the Offline Files Folder

    You can open the Offline Files Folder and delete files directly from the list of offline files. Deleting a file this way removes it from the cache regardless of whether it was manually or automatically cached.

    Note Deleting files and folders from the cache does not delete the network copy of the file or folder.

    If an offline folder is manually cached and you delete any or all offline files in the folder, the folder remains pinned. All files in the folder are cached the next time a full synchronization occurs.
    To delete files from the cache using the Offline Files Folder

    1.Click a folder, and then on the Tools menu, click Folder Options.

    2.On the Offline Files tab, click View Files.

    3.Click the files you want to delete, and then on the File menu, click Delete.

    In this view of the Offline Files folder, you can see which files are automatically cached (temporarily available offline) and which are manually cached (always available offline). If you delete manually cached folders this way, the folders and files in them are no longer pinned. You need to pin the files or folders to make them available offline again.
    To delete files from the cache on a network share

    1.Click a shared network folder, and then on the Tools menu, click Folder Options.

    2.On the Offline Files tab, click Delete Files.

    3.In the Confirm File Delete dialog box, select the shared folders containing the offline files you want to delete.

    4.Click Delete only the temporary offline versions if you want to delete files that were automatically cached. Click Delete both the temporary offline versions and the versions that are always available offline if you want to delete files that were automatically cached and files that were manually cached (pinned).

    Also you have the "Allow or Disallow use of the Offline Files feature" in the GPO, once you get there, click on Disable, The Offline Files is enabled by default on Windows XP Professional–based client computers and is disabled by default on servers.

    How to Restart the Offline Files Cache/Database

    The Offline Files (CSC or Client Side Caching) cache and database has a built-in capability to restart if its contents are suspected of being corrupted. If corruption is suspected, the Synchronization Wizard may return the following error message:
    Unable to merge offline changes on \\server_name\share_name. The parameter is incorrect.
    The Offline Files cache is a folder structure located in the %SystemRoot%\CSC folder, which is hidden by default. The CSC folder, and any files and subfolders it contains, should not be modified directly; doing so can result in data loss and a complete breakdown of Offline Files functionality.

    If you suspect corruption in the database, then the files should be deleted using the Offline Files viewer. After the files are deleted out of the Offline Files viewer, a synchronization of files may then be forced using Synchronization Manager. If the cache still does not appear to function correctly, an Offline Files reset can be performed using the following procedure:
    1.     In Folder Options, on the Offline Files tab, press CTRL+SHIFT, and then click Delete Files. The following message appears:
    The Offline Files cache on the local computer will be re-initialized. Any changes that have not been synchronized with computers on the network will be lost. Any files or folders made available offline will no longer be available offline. A computer restart is required.

    Do you wish to re-initialize the cache?
    2.     Click Yes two times to restart the computer.

    Each client would then have to re-configure their offline folders
