VPN won't resolve DNS

[Guest]

I'm trying to setup VPN access to my Windows 2003 SP1 server. I can
authenticate and connect just fine, but it won't resolve DNS lookups for the
Windows 2003 domain. I can still resolve my local DNS lookups as well as any
internet lookups.

Once I connect to the VPN, here is the ipconfig entry for it:

PPP adapter Test VPN:

Connection-specific DNS Suffix . : mydomain.local
Description . . . . . . . . . . . : WAN (PPP/SLIP) Interface
Physical Address. . . . . . . . . : 00-53-45-00-00-00
Dhcp Enabled. . . . . . . . . . . : No
IP Address. . . . . . . . . . . . : 192.168.10.154
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . : 192.168.10.154
DNS Servers . . . . . . . . . . . : 192.168.10.1
192.168.10.1
Primary WINS Server . . . . . . . : 192.168.10.1
Secondary WINS Server . . . . . . : 192.168.10.1

One thing to note is that the DNS server is assigned twice. I don't think
that's causing my issue, but wanted to point it out just in case.

Here are various ping and nslookup tests I tried:

C:\Documents and Settings\mezlo>ping gis
Ping request could not find host gis. Please check the name and try again.

C:\Documents and Settings\mezlo>ping gis.myvpndomain.local
Ping request could not find host gis.myvpndomain.local. Please check the
name and try again.

C:\Documents and Settings\mezlo>nslookup

gis

Server: [192.168.10.1]
Address: 192.168.10.1

*** [192.168.10.1] can't find gis: Non-existent domain

gis.myvpndomain.local

exit

When using my local DNS server (192.168.111.1), I can resolve local DNS as
well as internet DNS lookups. However, when I switch to my VPN DNS server
(192.168.10.1), it will only resolve internet DNS lookups. All attempts to
resolve 192.168.10.x DNS lookups result in the "Non-existent domain" error.
However, all lookups succeed when tried directly from the server itself or
from a workstation on the lan. It just won't work via the VPN connection.

I would greatly appreciate any help with this issue.
