My sbs server takes at least an hour to reboot. "Start" menu sometimes takes 10 - 15 seconds to pop up. All access to server is extremely slow causing time out errors on programs. Started 2 weeks ago. Don't know if this has anything to do with it, but, I started up Primavera (Scheduling/Contract manager program) and system slowed down. I thought it was just using too much memory so I shut it down. System didn't get any better. I have tried to uninstall program but it says it is missing a file and won't let me uninstall. Tried to re-install but says it can't read/write to a file and will not let me re-install. Since then, I have run McAffee several times. Uninstalled and re-installed and ran again. Ran Malware Bytes and only had one issue which has been removed. Subsequent scans come up negative. Tried loading and running TDSSKILLER but freezes at 80% of initilization. The system will not let me stop the process unless I re-boot. TDSSKILLER is using 50% of CPU. When not running TDSSKILLER, CPU is running less than 20%. Memory has 45% - 70% available. 364 GB free space on HDD. System: Windows Server 2003 / Small Business System - SP2 Pentium D CPU 3.40GHz/3.40GHz 3.37GB RAM My IT guy says the HDD and arrays seem to be running fine. Before we do a clean install, I need to know if anyone has seen this before and can help.
