no name resolution between 2 cisco 3640.

I have 2 ciscos 3640 routers connected with a T1. On one side the network is a 192.168.1.x and on the other side its a 192.168.10.x. I sit on the 192.168.1.x side. When I monitor traffic I get name resolutions on the workstions on my side but only IP's for the workstation on the other side. What is need in the router config to allow resolving ip to name between the 2 networks?

My DHCP and DNS servers are located on the 192.168.1.x network.

The nameserver that you have in the config should have all the records for both sides. If it doesn't then the remote site hosts are not registering with it or they have their own dns server.
It is a dns server issue and not a router configuration issue.
