offline changes not synchronized

Had a user that kept getting messages about "offline changes not synchronized". You could see that the server was online, but no matter what would not sync the changes.

This is Windows XP SP3 and connecting to Server 2003.

Found this Microsoft Support article that fixed the issue. Used the "Fix It" button, applied and rebooted.

Apparently the User's Offline Files (CSC or Client Side Caching) cache and database was corrupted.
