DNS across a VPN tunnel

Dear Experts,
      My company has a production environment (domain name = corp.company.com) and an office environment (domain name = office.company.com).   In the production environment, we have a set of Cisco ASA 5515 firewalls (managed by our datacenter) and at the office we have a set of Sonic Wall’s (managed by me).  I worked with the data center engineers to setup a site to site IKE tunnel between the sonic walls and I can now remote desktop and communicate with servers in the corp domain from the office domain and vice versa with no problems.  
      The problem is I can only access my servers on both sides by IP Address.  I realize there needs to be some form of DNS setup between the domains that I don’t fully understand.  I was able to setup a secondary zone on one of my office DNS servers that pulled down a copy of Corp.  I can now use a remote desktop session across the tunnel by using – computername.corp.company.com.   This works from the office to corp but not vice versa.  Do I need to do the same thing on the Corp side or is there just a better way to set all this up.
      Currently, all my servers are Microsoft Server 2012.

Would appreciate any and all help.
Thanks
John

Yes it will work if you create a secondary zone on the domain side. You can also setup DNS forwarders on the domain side to FW request to another DNS server.

Since you were the only reply Ill give you the points.  I was aware this could be done and once I set it up it did work perfectly. I was just hoping for a better way.
