Inetinfo.exe uses 99% of CPU

I have a Small Business server 2000 running Exchange 2000. recently we realised that we may have been victims of spam and unwittingly processing 1000's of emails an hour. I have that problem under control right now, but Inetinfo.exe has 98% of CPU time all of the time.
I can't stop Exchange services (they time out) and I can't stop or kill Inetinfo.exe
Am I right in saying that I have a DoS and how can I take control over this issue?
I have SP3 for Exchange installed but nothing has changed....
Can anyone help Please?

Regards,
Steff

hey steff, unplug the server's network cable, so that you can actually try to stop services. Then take a look at the applog, and see what's happening there. If anything of interest, copy and post it here.

If you cannot stop the services, shut down the machine thru normal procedures. DO NOT power off cold, it may corrupt the store if you do. Keep me posted...oh yes, Windows SP3 as well?

Hi David,
I am running SP2 for Windows ( I know I should have upgraded weeks ago). I unplugged the server, but no change in CPU usage. I finally managed to reboot the server and initially the CPU was using about 2% but after a couple of mins it was right back to 99% used by Inetinfo.exe.
All services have started successfully and the application log has the following errors:
Event ID:7229
Source: CheyDiscovery
Unable to send information using socket (EC=0)

Event ID: 1003
Source: IISinfoCtrs
Unable to query the IIS info service performance data

Event ID: 8197
Source: MSExchangeFBPublish
Error initialising session for virtual machine

I removed the modem eariler to prevent it's constant dial up's.
I have checked for viruses (Norton AV corporate)
and I can't stop any Exchange services..... they seem to time out and hang on "stopping services"

David... I'm lost!
Thanks once again for your help

Hi again David,
I have tried since to stop exchange services successfully... But the trouble seems to come from SMTP that refuses to stop..... could this be the problem area?

Hi David,
I rebooted the server in safe mode and disabled the SMTP service, I then rebooted and after the available services loaded I enabled the service and started it....inetinfo.exe hasn't used any more CPU resources and I have 98% available CPU............ That's fantastic but what is the problem any idea?

You should find the latest upgrade for the inetinfo and install it, go to the Windows Update site if you can. Take the Exchange services offline and disable them, then reboot and try to update.

If it still hangs after all teh updates and Exchange is online, we may have to empty out the queues, it could be bad messages hanging around. At the worst, you could have a corrupted metabase.bin file, which would require you to reinstall IIS, and then reinstall exchange. Let me know...

Hi David,
I've given you the points as you have been very determined to find a solution for me.......
The problem turns out to be (and I have no idea why as it's not a related piece of hardware) Video card, namely the ATI9000 PRO 128MB.... Christ knows what we have one of those in a SBS for! but once it was removed the CPU settled to 2% usage.
I haven't been able to thank you because we lost the server whilst installing service pack3 for exchange, upon reboot the hard drive was marked as "Read only" preventing anything from accessing the partitions.
Thanks again.

I appreciate it, but that's a weird mess. A lot of times, the problem is that not only does that video card need the latest drivers, but it also needs mini-port drivers for the AGP slot, and thoses depend on the motherboard type you have. I never would have thought of the video card causing the problem in inetinfo, but hey, whatever works :)
