Win2K rebooting with stop error 0b8

[mitsuman]

This is frustrating beyond believe.
Heres the setup:
Win2k Sp4, no updates available
Legato Networker 7.1.1
Server is rebooting randomly about twice daily with the following error logged by Compaq Notifier:Blue Screen Trap (BugCheck, STOP: 0x000000B8 (0x00000000, 0x00000000, 0x00000000, 0x00000000))

Any help is appreciated.

Are you running Tivoli Storage Manager?

No, nothing like that and its not clustered either so I'm at a loss. What do you think about possible memory leak causing this?

 

[aznluvsmc]

Memory leak? A possibility. Are you running the latest service packs and the system is up to date on patches? No Spyware or viruses?

No spyware, we're hoping its not a virus but we'll be scanning the MBR today. All updates are done, nothing more from WindowsUpdate. I'll also be checking the memory today as soon as the save sets complete and I can down the thing.
I'm out of ideas of what else to check, you recommend anything??
