I currently have one EX2003 server that is working good. I built a new one and have had problems with the system attendant. It was working fine for about a week. When I rebooted the server everything started fine. A week later the server will not start the SA. When you reboot the server it takes about a hour before the SA will restart, then you have to restart the Store and MTA manually. I had another server do this awhile back and thought something got corrupted so I wiped the server and started over and now the samething is happening.
