Weird VPN problem

I am working remotely and connecting to the main office through VPN.
Everything seem to be working except DNS names resolution for the
remote LAN computer names. I can ping computers by IP address.
The only machine that I can ping by name is a VPN/DNS server, but
it looks kinda odd. The IP address for this server fluctuates. It can
change from 192.168.0.3 to 195.168.0.27 and back during single
VPN session. 192.168.0.3 I was told is the real LAN addreess for this
server.
Now the other person who logins using different credentials claims he
has no such problem and all names resolved nicely for him.
What I am to ask my fellow coworkers to fix in VPN settings?
Sorry if my question is newbeesh :)

Thank you in advance.

Here some details on the connection in question:

I would say looking at the IPCONFIG /ALL that you sent that the problem is
that you have the dialup connection set to not use the default gateway on
the remote network. By default this is selected, but in your case it
doesn't look like it is.

How to enable this...
1. Open the properties for your VPN Connection
2. Choose the Networking Tab on the properties window
3. Click the properties button while you have TCP/IP Selected
4. Click the advanced button on the properties window for TCP/IP
5. Check the checkbox for "Use default gateway on remote network"
6. Click OK for the advanced TCP/IP settings window
7. Click OK for the TCP/IP properties window
8. Click OK for the Connection Properties Window

If you were already connected the settings will not take effect until you
disconnect and then reconnect.

Let me know if this helps.

First thanks for the reply :) Yes, you are right, the default gateway
on the VPN connection is disabled. If I enable it it just "kills" my
internet connection (by routing everything through remote LAN as
far as I understand). So I had to disable it.
Interesting enouh - it puts the assigned IP address as a default
gateway...

If you disable the "use default gateway .. " option, you keep your
default route to the Internet, but you only get a subnet route to the RRAS
client's subnet (ie the subnet corresponding to the "received" IP).

See MS KB 254231 for a description of what happens, and how W2k differs
from previous OSs.
 
Did this fix the problem though? When I do this at home and dial into work
I allow the default gateway to get set to the dialed in interface and then
in Internet Explorer I set my connection settings for my dialup connection
to use my work's proxy server. Now I can get back out on the internet
through the dialup.
