We have a Windows Server 2003 AD domain, which is named . It is in a two-way trust relationship with another AD domain and a DNS server in each domain is listed as a DNS server for the other domain (that is, I manage and my DNS server has a forward lookup zone for
The domains as I say have a two-way trust which is non-transitive. They are linked via a VPN (hardware controlled)
This all worked fine until we rolled out Windows 7 clients to nearly all users. Previously, accessing \filesvr.companyname.local worked fine and gave us the list of directories etc. For the Windows 7 clients this doesn't work, I believe because of 'DNS devolution'.
When I do an nslookup on a host in the trusted domain (like filesvr.companyname.local) it looks up a DNS entry for *.local.co.uk which is obviously not my internal file server at the remote location!
I have tried turning off the domain devolution setting in a GPO but it didn't seem to make any difference. What I can't understand is that my AD controller is the only DNS server listed in the clients' network setup, with no backups listed, so DNS queries go through my AD controller, and it seems to completely ignore the fact that the zone is one it already has fresh records for.
Do I need to turn off the domain devolution setting on the server?
