Cisco Unified MeetingPlace Release 6.1 > Web Conferencing > Configuring > Troubleshooting



If the server name in a URL request to the web server contains any periods, such as the dots in an IP address or a FQDN, the request is automatically routed to Internet Explorer's Internet Zone. Internet Explorer's default Internet Zone is configured to not pass Windows credentials to the web server.


Consequently, if you configured Windows authentication but used an IP address or FQDN when setting your web server Hostname [Home Page] parameter in the Configuring the Web Server, Internet Explorer prompts you for your Windows login information when you try to access Cisco Unified MeetingPlace Web Conferencing even if you are already logged on to your computer with your domain Windows account.


The following procedures provide instructions for two workarounds for this issue:


We recommend that you use the workaround provided in the To Add the URL String to Internet Explorer's Trusted Zone procedure.

  5. Click OK .
