Vista Sync Error on XP Share

I use offline files synchronizin shares on XP and 2003 server shares. ANy
file that I create or add while offline sync no problem if on a 2003 server
share, whereas I get a sync error for the files i save on the XP shares. I
get the error "The system cannot find the path specified" but the files are
there (on the client) and I can work on them. I have tried working on
permissions, opportunistic locking, etc. to no avail. I have the same issue
as this gentleman
