Windows Server 2003 ~ Terminal Services Licensing

Hello experts,

I am seeking to better understand the MS Terminal Services licensing model as it applies to three similar platforms I need to maintain, which are well past the end of manufacturing support. The platforms strongly leverage MS Terminal Services and are presently functioning, but I have valid reasons to believe the MS terminal services licenses might expire at some point in the near future--the TS licenses did expire previously when being supported by the vendor. I am unclear as to how they were updated.  The platforms do not appear to access a terminal services server.  I am attaching screen captures of the registry keys that are believed to be correlated with the terminal services licensing.  Any help in better understanding the MS terminal services licensing model in this scenario would be appreciated.TS Reg KeyTS Config ScreenTS License

-the TS licenses did expire previously when being supported by the vendor You had an SPLA agreement and EVERYTHING you didn't purchase outright should have expired once you terminated the agreement.
It appears that you had a license server installed at one time but currently don't Terminal Services should not be working without a valid license server.

One can rdp into any windows client o/s if they are a member of the local remote desktop users group with only 1 user at a time local users are booted off.  Server connections are practically unlimited simultaneous sessions with a terminal service setup and appropriate TS CALS.. Somewhere in purchasing they should have a receipt and the license keys for your CALS.  Purchased CALS don't expire ever.

FYI Server 2003 end of life is July 14th.
