I have two Windows 2008 R2 AD servers.
The first, xyz.com is in a large city with fast internet. There are approximately 12 users.
The second, foo.xyz.com, is in the middle of the bush on a satellite link, there are approximately 20 users.
The two servers are not connected to each other in any way.
I have a third office in a small town with slow internet access. I will soon be adding a server in that office, which has 7 users.
My goal is to combine all of them somehow and setup Dfs.
I'm inexperienced in AD management and looking for guidance. I would like to start with connecting my two current servers.
