Discovery: To figure out what’s going on we need to check how many licenses are currently in use and confirm that Citrix is actually successfully pulling from your license pool.
1) Open a command prompt on your citrix license server, type cd\ to get to the root of the C drive, then paste the following: cd “Program Files (x86)\Citrix\Licensing\LS”
2) issue the command: LMSTAT -a -c “C:\Program Files (x86)\Citrix\Licensing\MyFiles”
Or you can try it by leaving out the -c and the path.
Here we can see we have 33 licenses issued and 33 licenses in use and are all out of licenses.
3) Lets now look at which users are consuming the licenses:
from the same command prompt window, enter the command: udadmin -list
In this example, Kelly is no longer with the organization and needs to be removed from the list in order to release the Citrix license consumed by Kelly: udadmin -f XDT_ENT_UD -user kelly -delete
Note: replace the service name XDT_ENT_UD with the service name in your list, and kelly with the appropriate user name you want to remove
At this point you should now be comfortable with deactivating Citrix licenses, releasing them back into the pool for future use.
