We have a decent sized AD and Exchange set-up but have several remote offices that are not currently included. I am looking to connect one of our remote offices but AD is already set up there and functioning properly. I am looking to merge the 2 AD's together but have never actually done this. Also since they have always been the same company the names are pretty much the same. We have the main AD named company.com and the remote office is currently ca.company.com. I would not mind if ca.company.com became a subdomain of company. They were both initially configured as root domains. Has anyone merged domains that could point me in the right direction for doing this? Would it be easier just to blow away the remote office AD and rebuild it into the new AD? Another bad part is I am nowhere near the location and they do not have anyone remotely technical onsite so if something happens and I need to have physical access to the machine I cannot.
 
You could simply setup a dual trust between the two domains if you didn't want to have to merge them into one. Without having someone onsite that is technically proficient, I'd just setup a trust.

You will either have to set them up as trusts between the two forests, or you will have to rebuild one of your domains from scratch in the other domain's forest. The trust is much simpler.

Setup the two-way trust, and then you should be able to use the ADMT to migrate from one to the other.
