Server Defrag Caused all Vista Clients with Offline Folders to Fail

I ran a defrag on a set of folders that contained some network shares. All
Vista clients with offline folder setups for those network shares have lost
all access to those shares. Every file setup for offline access now reports
"Access Denied". I have tried disabling and reenabling offline folders,
formating the offline folder database, but hasn't worked. My Vista clients
have permanently lost all ability to use offline folder with that server.
They've been forced to use normal access, which works fine. Any XP clients
using offline folders remain totally unaffected.

Ideas?

FYI for anybody interested: Disabling encryption for offline folders cache
in the GPO bypassed the issue.
