VPN - using wrong DNS server

Hi,

we have the following problem
Client (XP) connects to VPN. The PPTP device gets the correct IP adress and dns server entries.
When I try to make a nslookup then I does not get the answer from the DNS provided by the VPN I get it from the local router.
Any idea?

Here is the Ip configuration and the result from nslookup i get when i am connected to VPN:

The solution in the end was to deregister one of our Domain names externally. We were using "Outlook Anywhere" and the external DNS would return an external IP resolution to our internal clients for example.

Once the domain was removed externally the problems went away. This question can be closed.

Thanks!

You can try and manually set the DNS on the  PPP-Adapter to 4.2.2.2

Control Panel->Network connections->Advanced (menu)->Advanced Settings

A list will appear, make sure the VPN is up the top...

I tried already to add the DNS to the PPP Adapter but it will be the same. When I add the DNS Server to the wireless adapter it is working, but that is not a solution for me.
Changin the priority in the advanced settings menu is also not working I tried it. I have the same problem when I use the LAN adapter.
I found in the internet that this is a known problem related to the provider with Generic Route Encapsulation. Do you have any other ideas?

regards

If it's an ISP issue with GRE then use IPSEC instead...
