I currently have a windows server 2003 domain controller at site a. I am adding another domain controller at site b which has an alwasy on vpn-tunnel. Site a- has ip of 10.X.X.X and site b has ip of 192.168.X.X. How can I setuo the backup domain controller at site b to communciate with site a. I also would want the clients on site b to access site b domain controller first and of course site a to access sites a domain controller firs.t I am not sure how to do this.

I am assuming that routing of both subnets so they can communicate with each other is already in place and a DNS zine for each subnet exists since you have said they are existing sites.

Within active directory sites and services you need to setup your different sites then create your subnets and IP connections.  If you do them in the order u gave listed then the wizards are fairly straight forward.

You then need to move the domain controllers into the correct sites and then right click on properties of NTDS settings under each domain controller name and ensure the global catalogue option is checked.

You will also need to create a site link between the two sites.   Take a look at my comment about half way down the question below.  I listed it out step by step
