Due to a large number of shift workers, we have a per device licensing scheme for terminal services. However, some offices have switched out a large number of devices in the last few weeks and the lifecycle of the CAL hasn't had a chance to run its course. So we ran out.
Anyway, it's easy enough to 'reg delete HKLM\Software\Microsoft\MSLicensing /f' on a laptop or workstation to trick it into getting a 90 day temp license till the storm blows over, but what about non-Microsoft clients?. We are now planning on replacing old linux terminal boxes with new ones in the next two months and I'm not really sure how I would trick them into getting new CALs, since I doubt they store the CAL locally like the windows RDP client, so I assume the info is cached server side, but I don't understand how. Any tricks?
