Server 2008 R2 with Server 2012, AD Trust and DNS Zones creation.

I support a client with two office which are connected with a site to site VPN. Office "A" has a Server 2008 R2 AD Domain, Office "B" has a Server 2012 AD Domain. I am looking for guidance how to create a trust between the domains and setup DNS domain at each site for the other to replicate DNS and be able to resolve by name resources on remote site. I have done some searches and reading but can't seem to find the correct solution, because the server names can non be resolved and are not trusted so can add to AD Domains and Trusts or DNS Zone for corresponding domain.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The proper way to do this is to set up a DNS stub zone in each domain pointing to the other.  For the trust, they'd need communication anyways so this should already be possible.  Then they'll be able to resolve each other's names, and thus be able to establish a trust.

I created the stub zones, without errors, however when I ping the servers from either end, there is no name resolution, IP ping works fine.

Don't test with ping. Test with nslookup. See what's going on. Logs and Wireshark if need be.

Sorry, that was a mistake, I meant to select your "Don't test with ping. Test with nslookup. See what's going on. Logs and Wireshark if need be." comment. How can this be fixed?
