I have one domain controller (DC) in one location and a failover DC in another location. For some reason, there are a few computers in the first location when logining into the domain login into DC2 (the failover DC) rather than DC1 (the "main" DC). Anyone know why that is and how I can force these computers to login into DC1?

You have to configure Sites and Services in AD. You need to create your subnets, and associate them with sites. Then, when a machine tries to contact AD, it's subnet will tell it what site it's in, and it will start with the closest DC(s) to it, which would be in its site.
