Cannot Connect to UNC Share on Small Business Server 2003 using built in VPN

I have one computer that will not let me map out a drive to the SBS 2003 server when the VPN is connected. I can ping the IP Address and NetBios name, but when I type \\servername I get an error that it cannot be located. I have tested on 2 other systems and they work perfectly. The client in question is running Windows XP. This feature also use to work on this client. Not sure what has change to prevent the mapped drives. Any ideas?

allready tried \\ip.adress.1.2.

If this works then run the command: nbtstat -R which flushes the netbios cache
there's are some more caches to flush, see link

Does \\servername.local\sharename work?
If so likely the DNS suffix is missing from the VPN/virtual adapter. If using the SBS VPN client (Connection Manager) it should add this automatically, but if not there with an IPconfig /all, add manually. DNS must also point to the SBS. See:

Sorry above \\servername.local should read \\servername.domain.local

I have tried the FQDN. Also, keep in mind it works on other machines. Just not this one.

Hi,

maybe you have the changed th option fulltunnelsupport on your vpn connection?normally a problem in connection to unc is normally based on DNS issues, If you use the ip instead of the server name for connecting does it work?
