Promoting an esisting Exchange Server to a DC

Posted on 2006-07-13

I have a Windows 2003 AD infrastructure in place with Exchange 2003 loaded on a member server.  I would like to promote the Exchange 2003 server to a domain controller (for disaster recovery purposes) but do not know if that is possible.  Can this be done without jeopardizing the Exchange organization?

it's not recommended to run exchange on a dc.
once exchange is installed, it is NOT supported to promote it to a dc.

what type of disaster recovery are you hoping to achieve?

They have a seperate server which is stored offsite.  We were hoping to be able to restore their current backup of 2 servers which is in their Exchange server to their offsite server using Veritas Backup Exec.  We've accomplished this with other clients but when planning this installation we did not take into consideration restoring Exchange to a different server name.  This configuration is needed for SOX compliance.

this might be a bit more involved than what normally transpires on this forum. but, are they looking for dr in the sense of 'this is what we're doing tomorrow if our building is swept away tonight'?

if that's the kind of dr you're talking about, there are a number of ways that could be done.

i'd probably read the following to start:

is this offsite system accessible via the internet? does it have a secondary mx pointing at it? is it part of the same exchange org as the live server?

it might be best to find a consulting who has done similar setups to assist with this design.

Yes to all.  We've done this before with other clients but their Exchange servers were all domain controllers due to the size of the organization.  It was bad planning on our part as we were rushed for the quote.  Thanks for all of your help, I truly appreciate it.
