At home, and I am connected to my ISP via cable.

On home computer (Windows XP SP2) I created a PPTP VPN connection in Network
Connections, which I use to connect to company server. In TCP/IP properties
of the connection I've manually put DNS addresses of internal DNS servers. I
also checked "Use default gateway on remote network". I also put this
connection in first place in Advanced Settings-> Adapters and bindings.

When I connect to my company with this connection, it works, but all names
are still resolved with my ISP DNSs. Why is this happening, what have I
forgot? I need to, when I connect to my company with this connection, to use
internal DNS servers.

Do I have to change something on the server or on the client?
 
That should work. Have you also added the DNS suffix for your company to
the VPN client settings?

Yes, I also did that. (I forgot to mention). It still does not work.
 
We have the same situation. It's not been a problem, since our nurses
only use it to synchronize their laptops with a server and the server is
identified via an IP address.

I've found that adding a HOSTS file with the necessary definitions will
allow full name resolution....

Today I tried to detect the packet flow.
I used two ethereals at the same time: one for VPN interface and one for
ethernet card interface(ISP via cable). Then I tried nslookup.

On VPN Interface there was standard DNS query and response. So it does
contacts internal DNS servers.

On ethernet card interface there was nothing.

BUT, nslookup says: Server:<ISP's server>, and then gives resolved IP. Why
does nslookup says that? Is it a bug in nslookup? To Microsoft: Please try
that and confirm is this a bug.
 
I am having a similar issue. My clients are using a Cisco VPN solution and
random clients will register their "A" records as their local LAN IP and not
the VPN Ip address?
