The computer is running Internet Explorer 6.
You use a network shared folder as the Internet Explorer Favorites folder.
You configure this network shared folder as Offline Available.
You add a file to the Favorites folder during a period when the network is unavailable. This step modifies the Offline File cache.
When this problem occurs, the registry subkey for the Favorites menu resets to point to the %windir%\Favorites folder.
Note The Favorites menu uses the following registry subkey:
This problem occurs because the Client-Side Cache (CSC) Offline Sync Manager denies access to the shared folder when the network is unavailable. When the CSC Offline Sync Manager denies access, it synchronizes the folder content in the local cache from the server.

Restore the computer network connection.
Close Internet Explorer 6.
Click Start, click Run, type regedit, and then click OK.
