Just yesterday I changed the primary AD domain on our network from access.domain.net to access.domain2.com. Ever since I did this, I can no longer access the Exchange 2010 server. I tried uninstalling the Client Access Role and the Hub Transport Role. I was able to successfully remove the Client Access Role, but couldn't remove the Hub Transport Role. I recieved this error when I tried uninstalling that. Summary: 6 item(s). 1 succeeded, 1 failed. Elapsed time: 00:00:12 Preparing Setup Completed Elapsed Time: 00:00:10 Hub Transport Role Failed Error: The following error was generated when "$error.Clear(); foreach ($a in (get-receiveconnector -server $RoleFqdnOrName -DomainController $RoleDomainController)) { remove-receiveconnector -Identity:$a.Identity -DomainController $RoleDomainController } " was run: "Exchange server "win-serv.access.dyn-net.com" was not found.

No Exchange servers are available in any Active Directory sites. You can't connect to remote Powershell on a computer that only has the Management tools role installed. It was running the command 'Discover-ExchangeServer -UseWIA $true -SuppressError $true _______________________ After that I tried to remove Powershell and try to remake the virtual directory but failed because it gave a similar error saying that it couldn't connect to the exchange server.

Is there a possibility that I could somehow remove exchange from the server and reinstall it?
