Can connect the vpn client but cannot access network resources

Posted on 2006-11-13

What happens, is that i can ping ip's on the inside interface of the pix, but i cant browse the servers via \\servername.

However, if i pull up a cmd line, i can do a nbtstat -A 192.168.10.x and once it resolves the name, i can then browse via \\servername.

It sounds like a dns problem, but the vpn group has the for dns and then an outside dns from isp. this is the same dns setup that our internal lan uses. Does this need to be changed?

Here's the config

PIX Version 6.3(5)
interface ethernet0 auto
interface ethernet1 auto
nameif ethernet0 outside security0
nameif ethernet1 inside security100

Add a WINS server to the network, add that WINS server IP to the VPN client config.
Else create a LMHOSTS file on the client PC that has only two lines in it to resolve the domain and the domain controller
