Lync 2013: Control Panel HTTP Error 401.1

I am working with Lync/OCS –> Lync 2013 upgrade project. I installed Lync 2013 on my Windows Server 2012.

Issue: When I try to access Lync 2013 Server Control Panel from the Front-End Server I get “Http Error 401.1” after three unsuccessful logon attempts. I can connect to the Control PAnel from other machines though (with the same credentials set)

Resolution: Fortunately I found this thread and followed Lync MCM Jeroen Reijling advice:

Logon on to the Front-End Server with an account that is member of the local admins group

  1. Start “regedit”
  2. Go to “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa”
  3. Right-click the Lsa registry subkey, point to New, and then click DWORD Value
  4. Type DisableLoopbackCheck, and then press ENTER
  5. Right-click DisableLoopbackCheck, and then click Modify
  6. In the Value data box, type 1, and then click OK.
  7. Exit Registry Editor, and then restart the server.

Now Control Panel is accessible:
