Problems after Exchange 2003 Domain Controller demoted

Posted on 2012-09-05

I'm visiting a supported site tomorrow where someone has demoted a Domain Controller that was running their only Exchange 2003 Server.  Issues include Exchange Services not starting, Exchange Server Manager not starting and RDP access failing. First thought is to try promoting it back but wondered on the wisdom of this? The Information Store is safe and backed up on another Server, Exchange Server name I have but not the Exchange 2003 Site name which from memory I need for a recovery build.

I had hoped to get remote access prior to visiting but this is impossible. Has anyone been there and fixed this type of problem? Suggestions very welcome.

    Yeah...DCPromo on an Exchange server that is installed on a DC isn't supported by Microsoft for this very reason. It basically causes all kinds of havoc. Re-promoting the server isn't really likely to fix the problem and could actually make things worse. My recommendation would be to rebuild the server and restore your mailboxes from the backup you have.

    Thanks for the very prompt response. Yes, we drew this to their attention but hard for them to understand. I'll have to check onsite about a mailbox backup tomorrow. Is there any way to determine the site name of an Exchange Server 2003 with System Manager inoperative?

    You can probably dig through ADSIEdit to get information about Administrative Groups and server names. Most of that is in Configuration>Services>Microsoft Exchange but I don't have an Exchange 2003 server in my test network right now to get specifics for you. AD site is determined entirely by IP address, so that's easy enough to get.
