Install the Remote Desktop Session Host role through Server Manager. This configures the server to accept multiple user connections properly. 2. Configure RDS Licensing
For administrators who prefer not to run third-party executables, manual hex editing is the most direct approach. This involves using a tool like to find and replace specific byte sequences. The Process:
Use open-source tools from GitHub like fabianosrc/TermsrvPatcher or RDP Wrapper Library .
Modifying system binaries to bypass connection limits violates the Microsoft Software License Terms. This can lead to compliance issues during software audits. Standard Alternatives to Patching
Open termsrv.dll in a hex editor (like HxD). Search for the specific pattern matching your Windows Server 2019 build version and replace it.
is a pure PowerShell script that directly modifies the termsrv.dll file on disk. It does not rely on any external binaries, making it easy to audit and run in restricted environments. The script automatically detects the Windows version and applies the correct byte pattern for Windows Server 2019.
Using third-party pre-patched files or automated patch executables can introduce malware or backdoors.
Instead of manually editing hex code, many admins use the available on GitHub.
By default, Windows Server 2019 (similar to Windows 10/11) limits Remote Desktop Protocol (RDP) sessions to . While this is suitable for administrative tasks, it restricts the server's ability to act as a multi-user environment without purchasing expensive Remote Desktop Services (RDS) Client Access Licenses (CALs).
Navigate to the System32 directory and grant your account full control:
The allows administrators to bypass default Remote Desktop Protocol (RDP) limits to enable multiple simultaneous user sessions without purchasing expensive Remote Desktop Services (RDS) Client Access Licenses (CALs). Out of the box, Windows Server 2019 restricts connections to exactly two concurrent administrative sessions . If a third user attempts to log in via RDP, the system prompts them to disconnect one of the existing active sessions.
