On a Windows Vista-based client computer, you can still access offline files even though the file server is removed from the network

On a Windows Vista-based client computer, you can still access offline files even though the file server is removed from the network. Additionally, you can delete the offline files and the temporary files in the Offline Files item in Control Panel.

Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To resolve this problem, reinitialize the cache of offline files. To do this, follow these steps:

1. Click Start, type regedit in the Start Search box, and then press ENTER.
   If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
2. Locate the following registry subkey, and then right-click it:
   HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\CSC
3. Point to New, and then click Key.
4. Type Parameters in the box.
5. Right-click Parameters, point to New, and then click DWORD (32-bit)Value.
6. Type FormatDatabase, and then press ENTER.
7. Right-click FormatDatabase, and then click Modify.
8. In the Value data box, type 1, and then click OK.
9. Exit Registry Editor, and then restart the computer.

Note Make sure that files are synchronized before you add this registry entry. Otherwise, unsynchronized changes will be lost.
