We recently moved 40 Win2k/Exchange 5.5 member servers from an NT4 domain to AD and suffered zero adverse effects. I'll assume your Exchange server is a member server. (If your Exchange server is a DC, sheez, I'll have to defer. It would involve a lot more than a domain change, and I don't think it would be pretty.)
If your Exchange services are already running under an AD account (via trust), then it should just be a matter of changing the domain membership of the mail server(s) and rebooting. If your Exchange services are running under an NT4 domain account, it is still just a matter of changing the domain membership and rebooting, but you will eventually need change the Exchange service account to an AD account before the NT4 domain is collapsed. (See link for changing service account. I assume you know the potential hazards of changing this account.) It should not matter if you move the Exchange server(s) to the AD before or after Exchange is running under the new service account, but I would only make one change at a time (domain membership or service account). In either case, make sure the service account is a member of the local admin group on the Exchange server once the domain move is complete, before the Exchange services are started. Believe it or not, on some servers, we were able to start all Exchange services without the service account being in the local admin group. We didn't catch the problem until the backups failed. Also, ensure that your Exchange server(s) DNS settings/entries are correct once the move is complete, especially if you have multiple Exchange servers. You could also migrate the service account and Exchange server to the AD using an AD migration tool of some 3P vendor. http://support.microsoft.com/default.aspx?scid=kb;en-us;266041 Russ -----Original Message----- From: Davinder Gupta [mailto:[EMAIL PROTECTED] Sent: Monday, August 25, 2003 5:59 PM To: Exchange Discussions Subject: Changing domain membership on Exchange server Shortly, we will be eliminating an NT 4 domain and I was wondering if we disjoin an existing mail server from NT4 domain and join it to Active Directory, will it have any adverse impact on us?
