I have a client that is running Windows Server 2003 R2 and is running extremely slow. The server was installed last year, but it gradually got slower and now it is unbearably slow. After troubleshooting I found that taskmgr.exe was using roughly about 50% of CPU usage (reason I say roughly is because it fluctuates between 48 and 52). After rebooting I see that explorer.exe used roughly 50% as well and then after another reboot, services.exe is using roughly 50% as well. So explorer.exe and services.exe alternate between using the other half of CPU usage, but after a long time only taskmgr.exe is left using 50%.
I have searched the internet for a solution but none of the stuff I found helped. Ok in safe mode it works fine and fast with no problems. I tried stopping services one by one until all where stopped and it was still slow. I scanned with Kaspersky and it came up with nothing. I had experience with viruses before so I looked in the registry for anything odd and couldn't find anything. Under startup there are only a few items and all of them I configured to startup. One forum said it was an update that caused the problem, so I left Automatic Updates running last night to see if that works.
Any help on this would be GREATLY APPRECIATED Thanx.
P.S. I know I haven't run any anti-malware/spyware programs, the reason for this is 1. it is too slow to install anything (it took me 2 hours to install HiJackThis) and 2. I don't think it has malware/spyware (I could be wrong) because apart from the slowness there is nothing suspicious about it, every program works fine, registry has nothing odd (well to my knowledge) and I have clean out temp files etc. with no problem.
If you require any more info please let me know.
