I don't have much experience with TS CALs but due to us running out recently I had to get up to speed on them, however I have a query if a more experience user out there can help.

This page: http://www.msterminalservices.org/articles/Terminal-Services-CAL-Alloc...on-Proc

states that:

The license server runs a process every 24 hours to recover CALs that have expired and place them back into the pool.


But when I look in the TS Licensing UI I see CALs there that have expired recently and even ones that expired years ago.

Does that mean that CAL recovery is never being run on these license servers and if so what is the best troubleshooting method for this?

Any help would be much appreciated.

Thanks,

cw

From
Expired TS CALs are not returned to the pool of available licenses

If Microsoft's Volume Shadow Copy Service (VSS) is running on the server, it could stop the thread on the TS License Server which reclaims expired licenses.

Stop and restart the TS Licensing Service - it will restart the thread, and, if the bug is the culprit, expired licenses will be returned to the pool of available licenses within a couple of minutes after the service is restarted.
