Terminal Server Licensing Manager Activation Issues 0xC011011 and 0xC0010020

December 6, 2011 by Wayne Small 10 Comments

I was activating a TS Licensing Server today on SBS 2008 and had a problem activating it as you can see from the screen shot below.

Additionally, in the Windows System Event log, I had the following error.

Log Name:      System
Source:        Microsoft-Windows-TerminalServices-Licensing
Date:          6/12/2011 1:38:02 PM
Event ID:      38
Task Category: None
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      server.domain.local
Description:
The Terminal Services license server cannot issue a Terminal Services client access license (TS CAL) to the client because of following error: Can’t add certificate to store, error c0010020.

It didn’t take long to track down this on the Microsoft support site to a known issue with a known fix.  This MS KB Article here explains it all.

Downloaded and applied the hotfix and after a reboot, the problem is gone!

    I once again find myself spending way too much time both reading and posting comments.
    But so what, it was still worth it!

    When someone writes an piece of writing he/she maintains the thought of a user in his/her brain that how
    a user can understand it. So that’s why this piece of writing is great.
    Thanks!
