Unlocking Concurrent RDP Sessions on Windows Server 2022 By default, Windows Server 2022 allows only two concurrent Remote Desktop Protocol (RDP) sessions for administrative purposes. If you need more users to connect simultaneously without purchasing full Remote Desktop Services (RDS) licenses, you typically have two options: legitimate group policy configuration or unofficial "termsrv.dll" patching. Option 1: The "Termsrv.dll" Patch (Unofficial)
Forums like ru-board.com (RDS subforum) sometimes contain patched DLLs for specific Server 2022 builds. They are labeled "эксклюзивно" (exclusive). Approach with extreme caution – download only in isolated VMs.

By default, Windows Server 2022 allows only two concurrent RDP sessions for administrative purposes. If a third person tries to log in, one of the existing users must be kicked off. To officially support more users—such as for a remote workforce—Microsoft requires the installation of the Remote Desktop Services (RDS) role and the purchase of Client Access Licenses (CALs).
