Hi all,
I cannot resolve host names over my Windows 2000 Server PPTP VPN connection.
I can ping all hosts by IP Address, but pings by netbios hostname and FQDN's fail.
I can connect to the PPTP Server by hostname and access it's resources, however, I cannot connect to other nodes on the network by hostname.
Server OS is Windows 2000 Server SP3, All Network Clients are Windows XP.
Server is the DC running DHCP, DNS, WINS, RRAS and is also the primary file server.
I have a reverse lookup zone specified in DNS for 192.168.0.x
VPN is allocating IP Addresses to clients using DHCP, which has been configured to dish out the IP address of the server for WINS and DNS
Server is behind a Linksys Router. Router is configured to port forward 1723 (PPTP) to the PPTP Server. I assume I'm correct in saying that there should not have to be any other ports open - the PPTP should be all that is needed.
DNS functions as expected on the network - it's only causing problems over the VPN.
I'm hedging my bets on this being a configuration issue relating to DNS (hey, Microsoft recently said that 70% of AD problems were related to DNS).
This is the only server in the network.
DNS is running in AD Integrated mode.
From a client connected over the vpn, an nslookup of any node on the remote network results in a "non-existent domain" error.
Relevant info:
ipconfig /all on connected client

Default Gateway is blank here because I have chosen to untick the "use default gateway on remote network" checkbox under the advanced properties of the VPN. (interesting aside - even with this selected, I cannot ping websites, but I can still use IM and pickup email - DNS must be routing something bizarrely here)
nslookup gibbsdc (PPTP server - main server)
*** Can't find server name for address 192.168.0.1: Non-existent domain
*** Can't find server name for address 192.168.0.2: No response from server
*** Default servers are not available
Server: UnKnown
Address: 192.168.0.1
*** UnKnown can't find gibbsdc: Non-existent domain
So, I believe the technical term is buggered.
Any thoughts or suggestions? Can't think of any other salient facts to help you out further at this stage
