Possible causes of "garbled" image files?

[aquanerd]

I'm running IIS 5 on Win2k Server. All of a sudden, image files that are being served are showing up in browsers as garbled. The pictures have huge artifacts randomly placed in them, and this changes every time you hard reload the page (ctrl+F5).

Has anyone seen this problem?

I think I figured out my own problem, so I'll post it:

I figured out that this problem started right after I installed Kazaa. Then I remembered that I had the same problem on another machine that was also running Kazaa. Under the Kazaa preferences, you can set it to listen to port 80 in addition to it's default port. This option is on by default, so you'll have to switch it off when you set it up. I think this is what was interfering with the transmission of image files to client browers.
