Question : Problem Mapping Drives to DFS shares over VPN

I have seem be having a problem with accessing network services via a VPN connection to my Win2k3 network.

When my users (using WinXP Pro SP2) make a VPN connection to the network they have problems mapping drives to the DFS folders.
 
For Example, if they map a to the DFS root (\\Domain\DFSRoot) they cannot connect. But if they map the drive to the full path (\\Server\Share) it works fine.

I have tried tracking down the problem:
1.     Ensure Enable NetBIOS over TCP/IP  -  OK
2.     Ensure “Enable LMHOSTS Lookup” is checked and LMHOST is correct   -  OK
3.     Ping PDC and BDC with NetBios Name  -  OK
4.     Ping other servers not listed in LMHOST with NetBIOS Name  -  OK

5.     netdiag.exe, however every time I ran it the problem disappeared till the next logon…
6.     dfsutil.exe, this seems to point out that the computer has not synchronised with the network, so if I wait for about 5 to 10 min after connection via the VPN and then try and map the drive everything works…

Can anyone help me? Is there a way to force the sync to happen earlier? Or with the command line?

If that works just write a batch with
net stop workstation /y
net start workstation /y
net start browser /y
exit

then put it on the client's desktop and train them to use it after connected
