Hi my issue is outlined as follows: After installing Windows 2003 Server standard and Exchange 2003, system manager was not installed. Furthermore, I cannot add it in as a snap-in in MMC. I have backup exec 9.1 running on the machine as well as Trend ScanMail for Exchange. Apparantly because System Manager was not installed, the store databases cannot be backed up and Trend will not scan the mailboxes. Apart from that I can do a bricks level backup of the mailboxes with the BE Agent for Exchange. The server is a Domain Controller in a child domain. It has Exchange 2K3 SP1 installed. Any assistance would be greatfully received. Regards, _______________________ MF
