Could you Mount the database with blank store and then try to uninstall Exchange. It needs database mounted to check if you have any PF if yes then it has to make sure that you dont own any replicas Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

Hi Vinod S PoojaryThe Exchange Information Store service does not start at all.The Exchange System Attendant service also does not start.So the uninstall requires a mounted DB to uninstall ?Any other ideas ?

If you are removing Exchange from a Mailbox server, remove the Exchange database files (*.edb) and storage group log files (*.log). Read the below http://technet.microsoft.com/en-us/library/bb123893.aspx If you can't make them to start then you have 2 options left 1. recover the server by /Recover Switch and then bring server online and make sure you donot have any PF or replicas in there 2. Manually delete registry entries and folders from server and delete the server object from ADSIEDIT The second one is not recommended by MS Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|
