ssl cert in IIS 6 works for Firefox, fails for IE 6 & 7

Hi,

I have a public server hosting multiple sites, some of which have secure
certs. Recently had clients telling me they get a "Cannot find server or DNS
Error" when trying to view a site in secure mode with IE, but have no problem
viewing it with Firefox. Until a week or so ago, there was no problem.

Configuration is Windows Server 2003, Web Edition, SP 2. Clients come from
the Internet and report the problems to the site owner. Tried loading the
home page with a https:// reference on IE 6 and IE 7; same error.

The site is behind a firewall; if I go to the intranet IP address in
Firefox, no problem. Using IE, same error. Adjusting settings in IE have no
effect. I suspect this is a server configuration (upgrade?) issue, but don't
know where to start in diagnosis.

Any assistance would be much appreciated.

Thanks!

Can you first configure IE6/IE7 to have "Show Friendly HTTP Errors"
unchecked.

And when you make the request, please look in the IIS logs on the web
server to make sure the request actually got to the web server. Either
in %windir%\System32\LogFiles\W3SVC#\*.log (if the request made it to
user mode but crashed) or %windir%\System32\LogFiles\HTTPERR\*.log if
there's something wrong with the request and it was rejected.

Please report the exact error response received by IE as well as the
exact error log entry from IIS. Based on that information, we can
formulate next steps.

It is generally not useful to randomly adjust settings in IE or IIS
without consulting what is actually wrong. Maybe you do not know
this, but the browser lies to you about what's wrong (part of making
the Internet "Friendly" -- hence "Show Friendly HTTP Errors" is
checked in IE by default), so one should never make troubleshooting
decisions based on what the browser returns.
