I had to re-install our SBS 2003 Standard. Hardware config unchanged. I did a full backup of all drives incl. system state and exchange etc. with ntbackup. I then did a new clean install of the server, rebooted in ad repair mode and restored the complete c: drive and the system state.
After reboot I only got to the Windows splash screen and before they screen turned to grey for the "Windows is starting up" screen the server reboots always at this point. Also safe mode did not help.
Is there any chance to make a complete clean install of the server and just to restore AD and Exchange without the entire registry and COM+ and whatever. ntbackup does not give me any choice than to restore everything. I would prefer only to restore the basic AD and exchange and start everything over from scratch. I have the last state of the server as a complete ntbackup and a mirror of all drives as well (done with another backup software).
