Window SBS 2003 hangs for no reason.
We have a SBS2003 server (completely up to date with SP2 etc etc) which seems to hang arounf 5 o'clock in the morning. Nothing seems to wok anymore. CTRL-ALT-DEL or whatever. HARD powerdown and restart works. The server will be up all day until next 5.08 or 5.01 next morning.
There is nothing in the log files, exept for "previous shutdown at 5.04 was unexpected"
The server is a HP ML350 G5 with 200i raid controller with 128 BBWC cache, 2X72GB SAS RAID1 for OS and 4X144GB SAS RAID5 SCSI for DATA. Server is up to date with HP Firmware maintenance CD 7.90 and HP Proliant Support Pack 7.90. We are running Symantec Antivirus Business Pack with GroupWare Symantec Mail Security for Exchange.
The server has been running ok for about 5 months and this is happaning for about 2 to 3 weeks now.
Thank you for replaying to this urgent matter.
