These days, we bought 4 "Device CALs" and set up.
After that, I checked RD Licensing Mnager to make sure it is working in right way.
The number of CAL is written 500 in the RD Licensing Manager some how, even though I bought just 4 licenses.
In the middle of construction work, I constructed the Licence Server within the workgrope without taking part in the domain. Does it cause this? Please give me a professor.
