Internal DNS Question

We bought another business and have taken over their office. For the next few weeks, they will still be running off of their domain server until we get everything switched over to ours. I have created a VPN tunnel between the locations that allows us to connect to them and vice versa. However, we are not able to ping between sites using the PC or server name, just the IP. We do have someone from our office working over there now and it hasn't been a big deal because they can just grab and IP from their server and it connects to email and other applications. However, not everything works, like our SharePoint site and I'm guessing it's because in the IP config of the machines over their, it's pointing to their DNS server, not ours. Is there way to connect the two?

If you can ping by IP, then set their DNS servers statically to your own servers.

Or create a Conditional forwarder in DNS on the acquired company's server for your domain and make sure you add the DNS suffix to the list of suffixes to search.  Either should work.

So, I can leave their IP config the same on the PCs, just add our DNS server instead? I'll give that a shot.
The only issue you may run into if you fiddle with their local client DNS settings is if they are still using the older servers for AD authentication.  Just be aware of you could end up with the "no logon servers available" if you take that route.

If there is no AD, screw it, and point it to yours.
