DNS will not resolve over a VPN connection?

Question

I have a user connected to a corporate network Via VPN but, the DNS will not resolve when she is connected.

Anyone have any ideas?

-Thanks!

Answer 1

Is this just a simple PPTP connection (using the built-in windows VPN client?)



Is the local network the same IP scheme as the VPN network (ie: both are192.168.0.x)? If so, change the local network to something else (such as 10.0.0.x) and try again.



Have you tried putting the DNS servers manually in the VPN connection (within the TCP/IP properties for the connection)? Or the domain suffix in the VPN properties?



Do you try connecting to machines with just the netbios name, or the FQDN? (ie: machine1 OR machine1.domain.local (replacing domain.local with your proper domain name))?



Update 1: Can you ping servers (or connect to them) using their FQDN (their internal one that is)?



If your run an ipconfig /all command in a dos prompt (from the machine that is connected via VPN), what do you see (would you mind posting it here)? (and only post the VPN connection's information please)

Answer 2

A VPN is a connection to a network from the outside of that network. Connections made to the internal network resources do not require DNS resolution because the connection to the network is "direct" to the internal network.

Answer 3

Try manually entering the ip addresses of the dns
