Help with Active Directory Remote Sites

Hello,
Right now I have a win2003 server at our home office set up as a DC for my network. I am trying to set up an addition DC to ship out to a remote site that will come online next month. I want to be able to administer the new site from here.

Right now the new DC is plugged into a switch and a router that I am using as a test platform. The new DC has connectivity to the internet and I have set up routes between the two networks, IE..I can ping across both networks.

My question is….What to do now???

I have went into Active Dir Sites and Services on my home DC and created a new site, a new subnet to reflect my new DC.

What needs to be done to connect the two.

I have done allot of reading on this but cant find the answer.

Please help.
