As a test, the following experiments were performed: The Terminal Services Licensing Service is running on a server running Windows 2000 Server with 2020 installed. On clients that may already have a temporary license, the registry branch HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSLicensing has been removed. On branded thin clients that were already connected to the server, Flash was reset (overwritten). No interventions were performed in stations that were not previously connected. A client program was launched on all client stations and a connection to the server was established. After that, the date on the server was returned to the current date. The connections went smoothly and after a date change on the servers and workstations in the range until 2019. Perhaps Microsoft will fix this problem in the near future. Roman For everything to work well, you need to know the following: 1) the 25-digit serial number (five times five digits) of the Windows 2000 server, on the basis of which the product code xxxxx-xxx-xxx-xxxxx is generated; 2) Based on the product code, a 35-digit license server code is generated (seven by five digits); 3) Based on the license server code, name, name, organization, and 7-digit registration agreement number, a 35-digit code of the key license package (seven by five digits) is generated. If everything is done correctly, we will receive the necessary license server code. To the question “Do you now want to install CALs on the license server with this product ID?”, we answer “Yes” and while we return to the Terminal Server, we return to the current window. If no warning is displayed and the message “The RD License Diagnosticer has not identified licensing issues for the RD Session Host server” appears, the RDSH server can obtain RDS CAWs for users.
Go to Administration > Terminal Server Licenses. We see that the server found on our computer is in the State Not Enabled. Right-click, for example, Enable Server. Select the type of automatic connection. Enter your personal data (first name, last name, organization, country – strictly those entered during the installation of Windows). I left the following page (email, address) blank. Let`s click Next and wait. Insert the license server ID as a licensing program, theoretically it should already be moved here from the previous window. Licensing program select Enterprise Agreement….
