This week our users began to experience problems accessing our Intranet based on a NetWare 6.5 box running Apache and using a Verisign SSL certificate. IE would say it was connecting but you would never get there. Firefox could get to the server but I had similar problems with Safari & Chrome.

I discovered that the MS security patch KB980436 had modified some portion of IE and was causing the problem. Uninstalling that patch put us back to where we could once again access our Intranet.

This seems to have something to do with how IE accesses using the SSL 443 port. When, internally, I accessed this same site using http instead of https it worked perfectly.

This patch was applied to Win XP and Win 7 with the same bad results.

If there is a more appropriate place for this post please move it there.
