I'm coming into this after several people have worked on the domain over the years.
We have 1 PDC called Val. Until recently, there was an exchange 2007 server at the same site. It died, there were no backups, so we're starting over. We have one other domain machine at a different site, it is not a domain controller.
In the past, I've seen messages in the 2007 server saying that it couldn't deliver messages to a machine called ex2000 (an older mail server that died a long time ago).
I've followed the KB articles and anything else I can find to remove the meta data for the missing domain controllers, but the ex2000 messages persisted, and now,trying to add the new exchange server to the domain, it's giving me "access is deined" and sites a machine called ex2007 (the recently dead exchange server).
Seeing all the issues with missing domain controllers, and the trouble I'm having adding this new server to the domain, I would like to start fresh and setup the domain correctly. My question is, if I run dcpromo on Val (the only domain controller left), would that wipe out all of the AD information and allow me to start over?
We are a small company, 8 users, new exchange server, one offsite server (on the domain but not a DC), and the PDC. All other machines do not log into the domain. I am aware that I will have to recreate users. Is there anything else I should be aware of? Or any other suggestions?
Thank you for any information you can provide.
