Remote Desktop Licensing (Terminal Services Licensing) is one of those things that is not well understood, and there hasn’t been a lot of quality documentation on it…until recently. The Directory Services team at Microsoft has written a good article that should answer all the questions you’ll ever have on Remote Desktop Licensing, such as:
- The different types of CALs and how they work
- License Server Discovery and how it works
- How the Grace Period really works
- Installing or Migrating CALs
- Lots more useful stuff
