This method, while effective, is the most error-prone and is for production environments due to the high risk of mistakes and the difficulty of tracking changes across Windows updates.
Check the following values: | Value name | Expected data | |------------|----------------| | LicensingCore | 1 (enabled) | | LicensingName | DNS or IP of your RD Licensing server | | LicensingMode | 2 (Per Device) or 4 (Per User) |
