Unauthorized: Authorization Failed


  • Hi Good Morning, I have successfully installed Lync Server 2013 in my network environment. However, when I try to open Lync Control Panel, it pop up the username and password. I did enter it and somehow it shows unauthorized credential.



    Unauthorized: Authorization failed.

    The application cannot verify your credentials.


    Verify your logon credentials and contact Your support team.


    I do add the username as a member of csadministrator on my RTCUniversalServer Admin on administrator account. I check the IIS features is set to Windows Authentication. I did install Silverlight 5.


    Can you help me what is going on. This is my 3rd time installation and yet the problem is still the same.
