Here's our situation: we had one server running Win2003 Server Std that was also the only domain controller. The ntds.dit file (AD database) became corrupted and there was no backup. We scrapped the DC and recreated the domain from scratch, using the SAME domain name and SAME server name.
Now we're down to Exchange. It's 2007 with SP1. It was running happily - just a single server (no frontend/backend). We have the original mail stores and backups of the stores.
I've searched high and low for this exact situation but have found nothing 100% on point. Some people want to migrate from one domain to another, others have corrupted Exchange databases and need to restore. In my case, Exchange was up and running fine, the AD was corrupted and rebuilt. Now I need help: do I completely remove Exchange and reload from scratch? Do I re-run setup /preparead and hope for the best? Are there other tricks to getting our Exchange server running again inside our new AD?
