That
reminds me of a funny situation.
During
the time of our complete network upgrade, we had a consulting firm coming in and
replacing some desktops and doing some informal troubleshooting at the same
time. This was before I started any of my training. Anyway, we had an old NCR
computer (anyone remember them?) that was a 486. The user complained that every
once in awhile, the screen would just go black, then flicker for a couple
of minutes, and then return to normal. This would occur every few
minutes. I swear these guys spent 30-45 minutes looking the thing
over, taking it apart, etc. Well I walked by and saw them all standing around
waiting for the computer to flip out again, so I asked what was going on. A
minute later the computer did just what they explained it was doing. So
I sat down, right clicked on the desktop, selected properties, turned
around and made sure they were watching, selected the screen saver tab, and
selected none. Then I got up, turned around, said "there ya go" and walked out.
I just
thought I'd brag a little bit since it was a memorable experience from early in
my career. Glad to see you got the problem worked out.

Subject: RE: 100% processor utilizationIt's amazing how you sometimes can't see the the forest for all the trees that are in the way. That was it!Don't normally ever run them and it got turned on on this guy. I should have been tipped off by how it was acting and I do remember(way back in my memory somewhere) about this being an issue. I'm not waiting so long before I get with you guys next time.Thanks to all that replied.http://www.sunbelt-software.com/ntsysadmin_list_charter.htm-----Original Message-----

Subject: 100% processor utilizationIt's a Dell 2200(266Mhz single processor), WinNT 4.0 Server SP6.0a, PDC(few local users authenticating), 256mb ram, plenty of diskspace, pretty stripped running only essential services(no IIS or anything like that). About 15 users use it for file and print services.Recently when it's idle(no keyboard or mouse activity) the Processor/% Processor Time and System/Processor Queue Length go up to %100 and 4-5 respectively. This is while we're monitoring bandwidth in/out(low) and disk activity(low). Interestingly enough when keyboard or mouse is accessed the processor drops to less than 5%(also drops when accessed with PcAnywhere) and stays there until it's idle again then it climbs back to around 100%. We are using Perfmon to see this which is pretty limited. I would think that the idle thread is causing what we're seeing on the graph if it wasn't for the queue climbing and users complaining about access being slow when it's happening.Mcafee Netshield hasn't shown anything but is currently disabled for trouble-shooting.Questions -1. Anyone have an idea what's going on?2. What's the easiest way to see what's actually using the cpu(Taskmgr shows Idle process up - all others minimal)? Do we have to add the scores of threads to the graph to try and find what's doing it?3. What's a good low end package for monitoring and diagnosing this sort of thing?4. Am I missing something?Any help would be appreciated.Terryhttp://www.sunbelt-software.com/ntsysadmin_list_charter.htm
