CPU on server at 100%

[kennysarmy]

Windows 2000 DC running file and print.
100% CPU occurs and task manager shows SYSTEM PID#8 is to blame.

IF I disable and renable LAN connection on the server it fixes it.

Has happened 3 times in the last month.

Any ideas?

i know you said its a DC running File & Print, but, does it run sophos becuase we had a similar problem on some workstations if you have then just reinstall sophos.

Hope this helps.

no sophos sorry - A/V solution is etrust antivirus by CA.

I can't see why disabling/enabling the LAN connection stops the CPU using 100%, that is really odd. What speed is it running at? 10/100 or Gigabit? You could try updating ethernet drivers.

As you're running 2000 server, have you applied all the latest fixes? i.e SP4 and the Update Rollup.

[kennysarmy]

Yes on SP4 and all windows update applied - also done the Compaq Proliant latest support pack.

It's running at 1 gig.

Suggestions have been it's something rogue on the network...but I don't know....

I would try an update of the ethernet drivers and a server reboot. I'd also monitor your memory consumption.

I presume you've also explored the possibility of viruses and spyware too?
