Offline Files

I have a number of folders that are made available offline on my winXP
laptop. I have changed some folder structures around on the server and the
synchronization now fails on some folders as they no longer exist. How do I
remove all references of my old folders on my laptop so that they are no
longer synchronized? I have tried Offline Files - Delete Files, CTRL+SHIFT
+ Delete Files, disabling and re-enabling offline files but everytime my
laptop still attempts to synchronize nonexistant folders. Is there any way
of completely removing all offline files from my laptop and then starting
again, only synchronizing the folders I need?

Thanks,
steve
