Can't map drive to a workstation across a VPN.

By ian.x.roberts ·
I am running SBS 2003 Prem. I also have 2 more 2003 Servers that are domain controllers in 2 separate physical sites. All sites are connected via PPTP VPN. The SBS uses it's own RRAS and ISA for routing and the other 2 sites have a Draytek router. All Servers and workstation are members of the same domain. The network is fully routed by way of static routes.

Everything seems fine replication works. Everything can ping each other by name or ip address.

Only problem is you cannot map a drive or browse to a workstation on another lan (ie via vpn) you can map a drive to a server on another lan (via vpn) or you can map a drive to a workstation of the same lan. Don't think it's an ISA problem as the problem exists also between the lans with the Draytek routers too.

I've been stuck on this problem for a while and would be eternally grateful if anyone knows the solution. Many thanks in advance.

Solved it....

by ian.x.roberts In reply to Let's start over

Guys, thanks so much for taking the time to help me with this. I finally cracked it. I was the XP firewall. When I first looked at this I discounted it as I could see file and print sharing was enabled by group policy and because I could get through it from another computer on the same subnet. I started looking at a number of things like SMB registry settings then enabling Netbios on the demand dial interface. I got WINS running. However looking closer at the firewall setting I noticed the file and print sharing had a scope of local subnet set. After amending the scope in group policy to include my other subnets and running gpupdate /force it worked.
