After Greetings, I have a problem... My Exchange server which was a Backup DC for my Domain just crashed. I don't have backup of system state and exchange database. so I don't have any other option apart from re-installing exchange server. so my question is how can I re-install exchange on new hardware with same name so that I don't have to reconfigure my clients once again. Option which I have are.... use ntdsutil to remove entries of old server. Install W2k as backup DC once again with same name Install exchange with same name and create mailboxes once again for all the users. so I need some expert comments ...whatever I am planning ...is it practicle...is this going to work. or is there any other way to achieve what is required. Thanks in advance Regards, Vijay Dogra.
