2000 server reboots about once a night

[Guest]

windows 200 Server on a Compaq ML330 Reboots almost nightly with the
following error logged in event viewer:

The computer has rebooted from a bugcheck. The bugcheck was: 0x00000050
(0xff76c000, 0x00000000, 0x80460689, 0x00000000). Microsoft Windows 2000
[v15.2195]. A dump was saved in: C:\WINNT\MEMORY.DMP.

Compaq's hardware check run for 48 hours showed all is ok. The rev. is SP4
and the most recent updates have been applied. Thorough virus and spy checks
reveal nothing. Disk space is more than adequate. RAID controller and disk
array checks out fine. This has been going on for about a month. All
thoughts will be welcome. Thanks in advance.

I would use the Task Scheduler to force a reboot at 3am
every night, in order to determine if the crash is related to
how long the server has been up and running. If it stops
crashing then you should look for an application with a
memory leak.

I would also use the Task Scheduler to invoke the batch
file below once every five minutes. It might give you a hint
about a particular program or service that is running at that
time only.

@echo off
set d=%date:~4,10%
set d=%d:/=-%
if not exist c:\Logs md c:\Logs
echo %date% %time% >> c:\Logs\%d%.log
net start >> c:\Logs\%d%.log
c:\tools\tlist >> c:\Logs\%d%.log
echo ====================>> c:\Logs\%d%.log
