Maybe i'm wrong, but it is not the idea of the sites? 
You create to different sites main and remote office, then you add some networks per site and the windows clients search the right dc and services.

The way to add DNS manually is, i think, a workaround and solves the problem temporary.

DNS lookup from application clients made by list on client, by default in windows 7 desktop clients list contain two fields.

if you write two not-remote DC in this list, why requests goes to third, remote DC?
