Can't remove old server from offline folder synchronization

[Guest]

I have 40 or so users who have mapped U drives for their personal folders.
Those users also have a My Documents folder that is homed on that U drive. So
the properties of My Documents is u:\My Documents. Then, that folder located
on their desktop is set to offline synchronize. Now for the fun. Over a
weekend I moved those files from an older server, set to be retired to a new
NAS. The location to them didn't change, it is still U:\My Documents but the
offline folders still sees it as the UNC of the old server. So... since those
files don't exist on that server any longer, I get an error telling me it
can't sync.

Now the question...

No matter what I do, it won't get rid of that server entry. I have tired
unchecking it, deleting all offline files, disabling offline files, rebooting
after each of these. Removing the server from the registry.

Any ideas?
