Locked

CPU maxed recently

By gralfus ·
I have 2 Windows 2000 Pro PCs that are experiencing maxed out CPU in the past week. My PC would max out every time the antivirus tried to do an update. The 2nd PC maxes out and basically locks up when defrag is started. I did some Windows Update installs in the past week on both, and since that is the only change that I'm aware of, I'm suspecting one or more of those updates.

Has anyone else seen this recently?

Yes, this is W2K SP4, and all the recommended updates from Windows Update (except the "rollup", though I did do that on one of the two PCs).

It only seems to be affecting the W2K computers. All the PCs at work are using XP and are not having this issue.

The defrag on the 2nd computer was Diskkeeper 7, but I also tried uninstalling it and just using the built-in version with the same results.

I was using Norton AV Corporate on the 1st PC, and live update would max it out and not allow a connection to the server. IT was working fine for years until the latest updates were installed. I suppose I could uninstall them, but some claimed they could not be uninstalled. (I have a recent image I made, so I could reinstall that and try loading the updates one at a time...).

I don't know if it's the updates in and of themselves. I have some pretty old machines running Win2K SP4 with rollups. And I have no problem with them locking up, however they are slower than they were without SP4 and rollup. What are the specs on the hardware. My oldest machine with SP4 rollup is a celeron 500 MHZ with 256 MB RAM and 6GB hard drive. If your machine specs are worst than this one. Then your problem is probably a result of loading SP4. However, if the machine is connected to your LAN and the internet you should remove it from your LAN without SP4.

This is an Athlon 1.6 (I think), and a gig of RAM. W2K SP4 worked fine for a long time on it. It wasn't until the latest updates that things went awry.

I would suspect some spyware or adware program is casing this. Have you run any programs like Spybot Search and Destroy or Adaware to look for spyware. The Microsoft Antispyware beta works on windows 2K as well.

Also check the process's running to see which service is maxing out the CPU. I had a process called Iostd.exe that was maxing out mine a while ago. Not sure where it came from or what it was and found a little info on the web which said to go to safe mode to remove it.

Hope this helps
Tom

I already scanned with AdAware and Spybot, no hits. I ran Task Manager before defragging and it was definitely the defrag process that had 99% of the CPU.

We've noticed for some time that Windows 2000 is just being loaded-down with basic baggage - all the updates, AV, etc take their toll even on a 'clean' system. If you installed XP on the computers currently running 2000 - again, even a clean install of 2000 - you will notice much better performance when running XP.

XP isn't an option in this instance, and W2K has worked fine until this last week.

I've been running a Win 2K network for years (all with sp4) and have never had this problem. Where it is a given that with all the MS baggage attach to Win 2K, it tends to bog you down, it does not bring you to a standstill.
From my experience in troubleshooting and repairing customer machines, I have found Norton software to be a severe detriment, and nothing more than a massive resource glut.
I'm sure that there are those who might disagree, but I have gone to great lengths to prove this to customers. I have reformatted their machines and completely reloaded them with all their software, while saving Norton for the last install. All the while, through the installing process of all other software, I monitored the system resources.
All was fine until the final Norton installation, when resources fell to all but none, and the machine fell back into the snail's pace it was in before the reconstruction. I had my non-believing customers witness these events alongside of me, just to show them it was not a case of bias on my part.
Take this for what it's worth, but experience has always been my motivation for actions required.
A good firewall, coupled with adaware, and a little bit of end user education is all that is really required to keep a machine well oiled and smooth running.
