In order to backup the Active Directory you choose the system state the domain controller and back it up. If your Exchange Server is also your domain controller (or one of them) then choose the system state on your exchange server. If you start the backup application on a Domain Controller and select the system state and look in the details pane you will note the one of the items is the Active Directory. This is where all the exchange user information is, which in fact is one in the same with your account information. Bill
