We are running Active Directory for our network (all Windows based). Single forest with 3 domain controllers.
We're in the process of doing some development work on a desktop application that will be used internally and make a few calls to an AD environment. However, since this is development we want to setup a non-production AD test domain.
Are there any problems in running two AD domains on the same network? It goes without saying that the test domain will have a different domain name, but I just wanted to make sure that I'm not pulling the pin on a grenade or anything :-)
