I have 2 servers doing this that use https. I was getting this on both port 80 and 443 but I followed the instructions on http://support.microsoft.com/kb/834141/ and resolved the issue with 80.
I am trying to figure out how to repair this on port 443 which I'm confused by since I thought the fix was per site not per port.
This is IIS6 on server 2003
The way I checked this was to telnet to my server then do GET / HTTP/1.0 command. I can't do this through telnet, however, with SSL as far as I know.
Thanks,
