Exchange Dag removal with NO Exchange installed
Posted on 2011-09-05
I have a situation with a Domain that previously had 2 Exchange servers in a DAG. A situation arose where we lost one of the servers, which had to be rebuilt. On the other Exchange server we couldn't get into The Exchange Server Management Console, as it kept trying to connect to the first exchange server, which currently does not have Exchange installed on it. Decision was made, probably wrongly in retrospect, to uninstall Exchange off of the 2nd Server, and just start the whole Exchange install from scratch
. Well Exchange did not want to come off voluntarily, so it was forcefully removed by manual editing of the Registry, and deletion of the Exchange folders, and finally by Adsi Edit. Now we are not able to re-install Exchange on EITHER Server, as it keeps failing with the message
"Exchange server is a member of a database availability group", this is using Setup /m:Recoverserver, as the normal setup forces us down that route. I have searched everywhere for a solution for DAG removal, but all the fixes I have seen require you to have at least access to the Exchange Command Prompt Console, and as one is a new server build, and one has had the Exchange removed from it, there are currently no Exchange Consoles available on the network. Can anyone suggest a way in which we can clean out any of the old references to any previosly installed Dags? Or any other suggestions?
Many thanks in advance
