Windows 7 and Offline Files - Sync at logoff

Question

All,
I have set up folder redirection in my organisation (testing purposes) The problem I am facing is Windows 7 will not automatically sync offline files back to the share.
There is a gpo for Windows XP to do this when a user is either is logging off on on. I am trying to accomplish the same when a user logs off and a script can be run to initiate a sync.
Please help.
This is the VBS script I am using, but does nothing when I run it. IS there something missing? A better solution?

Hi,
Please know that Offline Files in Windows 7 uses Bitmap Differential Transfer. Bitmap Differential Transfer tracks which blocks of a file in the local cache are modified while you are working offline and then sends only those blocks to the server. In Windows
XP, Offline Files copies the entire file from the local cache to the server, even if only a small part of the file was modified while offline.
How the synchronization in Windows 7 Offline Files works

That should be the cause of the issue that your script didn't work.
Considering that the issue should be related to the script, I suggest to post the question on Script Center forum for further help.
