Recovery after Exchange DC Demotion - HELP!

I'm well aware of the stupidity of trying to demote DC that is also an Exchange 2003 SP2 server.  We 'thought' between an image and other backups before the demotion we were sufficiently prepared for problems.  We were wrong.  Currently we have some functionality out of our Exchange box.  Mail delivery is working as planned and users are able to log in with Outlook and Webmail as long as they use the FQDN.

We're kind of stuck with where to go from here.  Do we attempt to fix the problems we're having (Can't add another mailbox, DNS Zones gone and can't add them to AD, etc) or do we rebuild the box?  And if we rebuild the box what is the best way to do so so it's only a member server and it retains it's IP and Hostname?

Do you have another domain controller that is a global catalog? It seems to point to the lack of GC/DC might be the cause. You need to look at what services you lost when that machine was demoted - this doesn't appear to be an Exchange issue as a domain controller issue. You would lose the DNS zones, but then you have no need for DNS server on this machine, so remove it and change the DNS servers in the network configuration to point to live valid domain controllers. Ensure that Exchange as well is using live valid domain controllers.

Why have you given me a C grade?
As you haven't responded to my question, I will appeal the C grade.

I refer you to the grading guidelines...

C: Because Experts' reliability are often judged by their grading records, many Experts would like the opportunity to clarify if you have questions about their solutions. If you have given the Expert(s) ample time to respond to your clarification posts and you have responded to each of their posts providing requested information; or if the answers, after clarification, lack finality or do not completely address the issue presented, then a "C" grade is an option. You also have the option here of just asking Community Support to delete the question.

Sorry, we figured it out on our own.  I appreciate the time you took to respond and hope the EE gods promote your question to a B or whatever you feel it's worth.  It doesn't look like I have the power to change your grade.
If you fixed it yourself, then you should have posted for a delete and refund.
The current "solution" isn't worth keeping in the PAQ.

As page editor I will reopen the question.
However while I could delete the question for you as page editor, I have a personal policy of not doing that for questions I have participated in.
