Exchange Server 2003 SP2 (standard ed.) All updates applied.
Dell Poweredge 1500SC
Monday everything was fine. The machine has been performing perfectly for months -2 weeks ago I re-applied exchange sp2 update to fix an issue. rebooted with no problem and system has been great until last night. When I came in the office this morning the server was no powered on. (UPS had run out evidently) tried to power up server and it would only get to booting to a point then instantly re-start itself. Was able to get past logon once and checked event viewer. No logs at all showing any trouble regarding booting or power -then another instant reboot. Its so fast there is no blue screen. No error log. The server doesn't know its crashing.
I was able to see one issue in Event viewer however which read: ' Unable to initialize virus scanning database engine." and a "SAVRT failed to load" error. These are Norton Antivirus related issues. so there Could be a problem with a virus restarting my machine. Anyone heard of one?
Things Ive tried:
Last known good config. - No luck
Disabled system reboot on error ( @ F8 option at start up) - No luck
booting in safe mode with and without networking : No luck- same rebooting problem.
Rebooting problem does not happen at exactly the same time every time in boot sequence. Was able to log on once for a minute. Next boot never got past "applying settings" Next boot lasted only a few moments, then the next boot a few seconds longer, up to a minute.
I believe a basic device is failing. RAM or Power supply. Though I think a RAM failure would catch a blue screen at least.
Trying next: booting from Norton CD to scan drives.
