I just got a warning from my firewall that c:\winnt\system32\ntoskrnl.exe tried to connect to an IP address.

The security log says "Windows Winsock binary change detected"

What does this all mean, if anything?

I know ntoskrnl.exe is the Windows NT kernal ... it isn't a worm or virus or something

The first means your kernel is trying to connect to something. I'm not sure if that's normal or not. The kernel is the very core of the operating system - the first thing that loads when your computer boots, and manages getting everything else going.

Your winsock binary changing could be normal or abnormal, did you do a windows update or install any software or anything? If not, I would perhaps be suspicious. I have limited knowledge of windows, but afaik, winsock is the windows socket library, responsible for all socket communication, including pretty much all network communication.

After I loaded the Win 2000 SP4 is when I started getting these warnings. I assume they are related, but I wanted to be sure. I got the warning a second time yesterday. The message said the file had changed since the last time the program was started and asked if I wanted it to access the network.
