Two DCs with the same domain name but never join eath other
Posted on 2009-06-29
One of my clients used to have two windows 2003 Domain Controllers and they were in the different locations. Both DCs have the same domain name but they don't join each other (e.g. DCa and DCb are the same name mydomain). Now, they close one of the offices and move DCb to the DCa office. The DCb also has Exchange 2003 installed. What is the best way to make them work together?
1. If they demote the DCb server and join in the DCa, does the exchange need to re-install?
2. I assume if they demote DCa and then join it in the DCb, the exchange should work, but we need to rejoin all workstations. Right?
Or any better options?
