AD DNS not resolving correctly across VPN link

I have a site to site VPN and clients are assigned an IP and DNS servers by the local firewall. The DNS server is on the other side of the VPN link.

When the client does a NSLOOKUP on a AD server name it fails, if I append the AD domain name to the query it works. How can I enable DNS lookups without appending the domain name to it?

I have an application that deploys using the server name only and cannot be reconfigured to add the domain name to the deployment url.

Running Active Directory integrated DNS on Windows 2008.

Thanks!

I assume your DNS is AD integrated? The client on the remote site gets the DC/DNS IP as first DNS server? Check the DNS suffix on the remote client, should be the full qualified domain name (i.e. yourdomain.local)

Hello,

All the clients are showing the correct DNS suffix, I was able to do a work around by using the advanced adapter settings and bumping the wireless connection to the top of the list. However I was not going to do this for every client so I set up a local DHCP/DNS server and then everything worked fine.
