We currently have a Network with three servers all running Windows 2003 server. A system file server (Domain Controller), a system Terminal server for remote operations and a system Exchange 2003 server. The Exchange 2003 server recently crashed and can not be repaired. We have another server ready to go running Win 2003 server. We are not concerned about the data form the old server since it was only up for about a week before it crashed. We can join the new server to the domain and reload Exchange 2003 but I know there will be a problem since the prior installed updated the AD on the controller. how can I remove the prior install in order to get the AD ready for a re-install of the Exchange 2003 server?
