Did you check the DNS you are using? If you are getting the DSL DNS, then you will still have the problem.
You need to be pointing to your internal network DNS (the remote end where you are vpning to) in order for the internal host names to be resolved.
If you are just going to use the DNS to lookup the local names, then you do not need to configure the netbios, if not, by default the netbios is sent with broadcast mac address. In that case you will not be able to map network drives etc as the netbios packets will not reach the end host anyway.
