Migration to 2008 A/D with Exchange 2007
Posted on 2011-09-12
I have the following environment and will answer any further needed questions regarding this as needed.
1 Exchange 2007 Server on Windows 2008 64 w/ A/D.
1 2003 A/D Server.
I would like to remove Active Directory from the 2003 server.
In the past, I simply ran DCPROMO on the 2003 A/D Server and Exchange stopped working.
I had to contact Microsoft to get it back up and running. Since the problem was from the A/D server being demoted, their solution was to have me run DCPromo on the 2003 server again and then ran /prepareAD and /PrepareDomain.
I was kind of shell shocked from the incident and decided to just leave it alone. That was a year ago and I'm ready to go ahead and move forward with removing A/D from that 2003 server.
What is the correct procedure for removing that A/D server without breaking Exchange again?
Also, I'm not sure why my 2008 A/D server did not work on it's own when I demoted the 2003 server.
Thanks in advance for your help.
