i'm running win2k server and have installed all the administrative tools even though i'm only using dns, dhcp, and routing services at the moment. i also run sql 2000 server, iis ( ftp, smtp with a downloaded mail server from the net)on the same machine...with a bunch of other applications like office, dreamweaver, flash etc....the problem is that my hard disk has started to spin constantly(doesn't stop)since the last 2 days... and if i try to shut the machine down, it gives me this message..."End Program - Socket Notification Sink"...after that my machine tries to end that program by itself but can't...and then it gives me those all too familiar options to "End Now" or "Cancel"...if i click on "End Now" the machine shuts down all right but only to start with the same HD spinning problem...and if i click on "cancel", it doesn't shut down...my pc has become very very slow due to this HD problem...and it's driving me nuts...I would really appreciate it if somebody could help me out and explain what a "Socket Notification Sink" is...
