Check Web Conferencing Server Virtual Directory Setting:
You do not have permission to view this directory or page using the credentials that you supplied because your Web browser is sending a WWW-Authenticate header field that the Web server is not configured to accept.
Go to Microsoft Product Support Services and perform a title search for the words HTTP and 401.
Open IIS Help, which is accessible in IIS Manager (inetmgr), and search for topics titled About Security, Authentication, and About Custom Error Messages.
Do you have a certificate installed on the default website directory in IIS on your front-end server & you've selected "require SSL" in directory security?
