I've got a rather weird situation. I recently virtualized one of our main servers in the company that had our DNS and Active Directory on it. We've recently found out that an old program on the newly virtualized server isn't functioning as normal so we'd like to revirtualize that server and just that drive to its own VM. We are nervous about reconnecting that server to the network since it had DNS and AD on it. We've uninstalled DNS from the server, renamed the server, and removed its static IP address, so it would get one dynamically.
My assumption would be, at this point reconnecting it to our network couldn't cause any major problems, but I wanted to get everyone's thoughts on that. Are there any other precautions I should take to make sure it doesn't cause any conflicts with our network or our current AD?
