Hi All,

Having changed the domain our 2012 AD Server is running on from domainv2.local to domain.com, in order to ensure valid wildcard SSL certificate can be used rather than a self signed with unmatched domain causing invalid SSL popups all the time, the Exchange 2013 server no longer works.  I should have looked at the implications to Exchange prior and from what I am reading there is no way to change the domain name used by Exchange as of 2003.

I currently cannot connect on EMS/ECP/OWA/Clients, and am slowly coming to terms with the fact that I will have to do a reinstall of the 2012 and exchange server on the new domain.

The current error I get on ECP is:

Server Error in '/ecp' Application.Cannot find information about the local server host.domain.com in Active Directory. This may be related to a change in the server name.

Can anyone please advise on the best procedure to follow to recover from this?  I want to keep as many settings as possible so that I can review them while installing the new server as it took some time to get it where I wanted it.

I assume that the main thing is to back up the database and the logs and then install using the same file paths.  But imagine there is a lot more that I will be able to retain if done properly.

Kind Regards,

Anthony
