The Universal Termsrv.dll Patch is a popular third-party tool used to enable concurrent Remote Desktop (RDP) sessions on Windows systems that normally restrict connections to a single user. For Windows Server 2012 R2, this patch (often created by a developer known as DeepXW) allows multiple administrators or users to access a server simultaneously without disconnecting one another. Key Features and Benefits
Concurrent Sessions: Removes the default limitation where connecting a new RDP session kicks off the existing user.
Administrative Efficiency: Essential for IT teams where multiple admins need to manage a single Windows Server 2012 R2 instance at once.
Stealth Operation: Unlike some other tools, patching the DLL directly can sometimes avoid detection by antivirus software that might flag wrapper-based solutions as "HackTools".
Automatic Backup: Most versions, such as Universal Termsrv.Dll Patch 1.0b, automatically create a .backup of the original file for easy restoration. How to Install the Patch on Windows Server 2012 R2
The patch typically comes in 32-bit (x86) and 64-bit (x64) versions. Since Windows Server 2012 R2 is almost exclusively 64-bit, ensure you use the x64 version.
Preparation: Download the patch and create a manual backup of C:\Windows\System32\termsrv.dll just in case.
Run as Administrator: Right-click the patch executable (e.g., UniversalTermsrvPatch-x64.exe) and select Run as Administrator.
Apply Patch: Click the Patch button. The tool will stop the Remote Desktop Service, modify the file, and restart the service automatically.
Restart: Reboot your server to ensure all system changes take effect.
Group Policy Check: Ensure your local policies allow multiple sessions. Run gpedit.msc and navigate to:
Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections.
