When you launch the Lync Server Control Panel Silverlight application from the Start menu or open https://lyncserver.domain.com/cscp in Internet Explorer, you must enter a username and password for an account that is a member of the CSAdministrator group in Active Directory. You may then receive the following IIS error:
Unauthorized: Authorization failed.This happens when the https://lyncserver.domain.com/cscp website is not in the computer's Trusted Sites zone. Here's how to fix it:
The application cannot verify your credentials.
Verify your logon credentials and contact your support team.
- Launch Internet Explorer
- Double-click the Security Options zone information at the bottom of the IE window:
- This will open the Internet Security Properties window. Click Trusted Sites and then the Sites button.
- Click Add and Close to add the https://lyncserver.domain.com site to the Trusted Sites zone.
Now you will be able to access the Lync Server Control Panel from both Internet Explorer and the Silverlight application on that computer.
I got the same error but no luck even I add the domain into trusted application. Any idea? - Ben
ReplyDeleteEnsure that the logon credentials are for a user who is a member of the CSAdministrator group in AD.
ReplyDeleteI use 2 accounts: administrator and csadmin (new created), and put those accounts into CSAdminstrator group already. No luck it still cannot be accessed with same error.
ReplyDeleteI am using with SQL 2008 SP1 and install "Enterprise" edition in topology builder. - Ben
The new accounts and group membership may not have replicated throughout the domain. Try again once replication has completed.

Hi all
ReplyDeleteIn my case, I was CSAdministrator and the webpage was in trusted sites, however according to the Error logs, the Lync server could not contact the SQL Browser service.
Have any of you who are still experiencing this problem received one of the following:
