Hey guys, This is sort of a long shot, but I figured I'd ask anyways, I don't know where else to go or anything else to do. Here's the issue. We have MS Small Business Server 2003 with Exchange. We are having problems with pausing and hesitating quite frequently. Our machines will just pause for 10 to 20 seconds at a time on average, with our longest pause at around 1 minute. We have looked at the applications running, the tasks, everything we can think of. We can't find what is causing the server to go search the network for something. When we are running MCM2 (roughly 12 players on Motocross Madness) we get a really bad jiggy screen. The FPS drops to about 4 for roughly 30 seconds. This is a random thing too, one day it hits one machine, then another. Another day, it hits two or three machines at the same time. We haven't noticed it hit the same machine day after day faithfully though, but it will hit the same machine for two days, then skip the machine for a day, then hit it again the next day. Do you guys have any idea what we could possibly look for ?? Do you guys know of a program we can use to watch for this activity that we may be able to find the culprit ?? Do you guys have any ideas you could throw my way in terms of diagnosing this ?? Thanks.
