First, we need to install the RD licensing role. The easiest way is to open the server manager and then click on the nodes of remote shutdown services. The CAL version must match the software version of the server it accesses. Older versions of CALs cannot be used with the newest version of the server software, but the newer RDS-CAL versions can be used with an older version of the server software. More information about this letter VL: www.microsoft.com/en-us/Licensing/learn-more/brief-windows-server-2012-rds.aspx. (same information valid for 2016) I also tried to install them by activating web portal activate.microsoft.com/. But it also ends in mistakes. As soon as the Deployment Properties window opens, click on the License RD menu. Select here the license mode we installed on the license server, then enter the license server into the fold bubble and click Add. The server may already be in the list, and if so, we will receive a message that will inform us: on the screen “Install the assistant for the installation of licenses” with the error message “The data of the license agreement provided to Microsoft is invalid”…: This screen may be different from yours, since I selected Enterprise Agreement in the previous one.
Nevertheless, it doesn`t matter, because whatever type of program you`ve chosen, all you need to do here is enter your license code or license number. Once you`re done, click Next to continue. I`m in the same boat as you. Purchased some RDS-CALs via the OPEN license and tried to install them by typing the activation and licensing numbers provided. Always the same mistake as you. Reason 1. You misunderstood the information on the RDS license. Reason 2. They are not connected to the Internet. Reason 3. The TCP 443 port (from) is blocked on the firewall (port 443 is required to communicate with Microsoft servers to activate RDS licenses).
Reason 4. You`re trying to install a bad version of remote CAL on your server. (z.B. try installing RDS Cals for the 2019 server on a Windows 2016 server). Click here to see the compatibility of the RDS CAL version. The specified license server is already present in the list. Enter a valid license server. The next step is to set up the license server in the broker to reflect the added licenses by navigating to Server Manager > remote shutdown services > preview, and then clicking The Tasks > Change the properties of the commissioning.
