Hello Everyone,

Our Exchange server was accidently deleted from our domain and now it doesn't show up in our Active Directory. Now, I can only log in locally.  I was going to try to re-join it to the domain, but I can't because of this note....

"The identitfication of the computer cannot be changed because - The Certification Authority Service is installed on this computer"

Just looking for some help resolving this.  Anybody have this happen to them before? Any insight?  Much appreciated.

You mean to say computer object removed from AD? Why don't you restore that object, using ADRestore.net tool and check if that works.

If not, then you might need to reinstall Exchange again in DR mode. What version of Exchange server you have currently.

Hi Everyone,

Sorry for the delay in posting back. We fixed the issue by un-installing the Certification Authority component. We then rejoined to the domain. Then re-installed the cert authority and re-issued the cert and all is well.

Amit, you suggested a re-installation...but of what? When I first saw your answer, I assumed you meant a re-install of the actual Exchange software on the server. Which was a suggested fix I saw on other sites. If you happened to say...."un-install the cert authority the re-install", then I would have accepted your answer. But there wasn't enough detail to know what needed to be re-installed.

jehoward, you didn't come back after that post for further clarification. If that is the case, i am not looking for points.

You can close it again. Thanks
