This probably is a very open ended question, but really I'm only looking for a specific aspect I suppose. It relates to a reboot question I posted earlier, relating to restart orders of servers, Server Restart's and Respective Orders. Please take a look if you get a second for input!
Basically - in relation to how Exchange integrates with AD, what would happen in two scenarios:
1). The Exchange server is booted up before the DC is online 2). You replace a DC but keep your current Exchange server.
I'm fairly new to all of this, so hopefully this isn't a silly question (I'm an apprentice in fact!).
