I need to add another Domain Controller to our Domain and I think I have narrowed down my best bet but I figured that I'd throw it out to you all and see what you think. Here's our setup: Windows 2003 Server - Domain Controller - Global Catalog Server, etc (this is the only current DC). Windows 2003 Server - Member Server - running Exchange 2003 Server exclusively, Windows Server 2000 -Member Server - Running two database programs. I was looking into making the Exchange Box a DC but I read that you cannot (or at the very least, should not) change membership of an Exchange 2003 Server after it's been implemented. So I'm left with promoting the 2000 Server to a DC. A couple questions - 1. Should I promote it? 2. Should I upgrade to 2003? 3. Should I make it a GCS and/or FSMO server? Any other thoughts/comments/snide remarks are welcome.
