Ditto on the screensaver - not only the 3gl but those that maintain continuous connections to the Internet   MJM Network Administrator   -----Original Message----- From: Miley, Dan [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 06, 2001 12:44 PM To: NT System Admin Issues Subject: RE: 100% processor utilization   you wouldn't by chance be using a 3gl screensaver? -----Original Message----- From: Bahm, Terry M. [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 06, 2001 3:34 PM To: NT System Admin Issues Subject: 100% processor utilization It'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.
