I will describe in this article terminal services licensing discovery methods in workgroup and domain.
In Work group there are two methods for discovering licensing:
License Servers Registry Key Query
go to the registry to key
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TermService\Parameters and create there new key “LicenseServers”. Now enter that subkey and for each license server create new key named “ServerName” where value [...]

Everybody knows that for access terminal services it is enough to open just 3389 ports and remote clients will be able to access terminal server.
For terminal services licensing to communicate between two servers there are few more ports that would need to be available.
This is for scenario when you have licensing server in one site [...]

Microsoft allows you tu use downgrade rights and if you lets say purchased licences for windows 2008 you can downgrade it to windows 2003. For full list of downgrade options please use link below.

Unfortunately that is not trivial job to do. There are few steps you will need to do in order to move terminal CALs.
1. Install Terminal Services Licensing on the new server

3. [...]

Many people will ask what is the difference between users and device CAL when purchasing licenses for terminal services. CALs have different scenarios that I will explain.
If you have more users than clients (like in a classroom, where multiple people connect to the Terminal services from shared client workstations), then per Device licensing is cheaper [...]

I have noted that sometimes some Wyse thin clients would require new device CAL from terminal services licensing every time they boot.
This is bug in Wyse firmware and it should be fixed by Wyse support team. It is only on some particular devices.
Why is this important?
Lets say you have 50 thin clients and 50 device [...]
