Releasing licenses from Citrix License Server 11.10.0

This is pretty easy actually.  

1. Right click the command prompt icon and open as administrator. (It won't work if you don't run as admin.
2. Navigate to C:\Program Files (x86)\Citrix\Licensing\LS
3. There you will find the udadmin.exe file.  This is how you will remove the licenses.

First run a list of all licenses in use by users and devices:  udadmin -list

To release a user:  udadmin -f XDT_ENT_UD -user {username} -delete

To release a device: udadmin -f XDT_ENT_UD -device {devicename} -delete

After you have deleted everything you need cleared just stop and restart the Citrix Licensing service.  When you rerun the -list command you'll see only the licenses still in use.

That's all there is to it.
