Remote Desktop Licensing Service Stopping

  • 아티클

Hello AskPerf! My name is Matt Graham and I'll be discussing an issue that you may see on your RDS Licensing Server.

SCENARIO You have both a 2008 R2 and an 2012 or 2012 R2 Licensing server in your RDS environment.  When you look under services.msc, you notice that the Remote Desktop Licensing service is stopped on the 2012 / 2012 R2 server.  You try to start it again, but after a short period of time (30 seconds to a few minutes) it stops on its own again.  In fact, every time you try to start the service, it starts for a short time and then stops on its own.

Alternatively, you may see this service crash.

ISSUE This behavior is actually by design.  You cannot have a 2008 R2 and a 2012 / 2012 R2 License server in the same RDS environment.

RESOLUTION If you are moving to a 2012 / 2012 R2 environment, then deactivate and decommission your 2008 R2 license server.  If you still want to have two or more license servers, you will need to build another matching 2012 / 2012 R2 license server.

CONSIDERATION #1 We have seen at least one case where the 2012 License Manager Service still did not start even after removing the 2008 R2 License server.  In this case, the licensing server database had become corrupt.  If this happens, you can rebuild the database using the "Manage Licenses" wizard.

WARNING If you do this, you will have to re-install your licenses after the rebuild. Be sure you have your licensing information.

1.  Open your RD Licensing Manager, right click on your server and select Manage Licenses.

2. Select Rebuild the license server database.

3.  After this, you will need to have your Retail CAL pack or your EA information in order to reinstall your licenses.

CONSIDERATION #2 In one case, a customer had to rename the "C:\Windows\System32\Lserver" folder, uninstall the RDS roles, reboot, and reinstall the RDS Licensing role in order to get the service to start again.  This should effectively do the same thing as rebuilding the license database, but I mention it because it was successful in at least one case.

Finally, when you decommission your old 2008 R2 server, be sure to think through what that will entail for your session hosts.  You may need to take inventory of your session hosts and ensure that they are pointed to your 2012 / 2012 R2 license server if they aren't already pointed to it.
