By default, administrative mode only allows two simultaneous sessions. For businesses needing more users to access the server simultaneously without purchasing expensive Remote Desktop Services Client Access Licenses (RDS CALs), modifying the termsrv.dll file is a common workaround.

Software like the "RDP Wrapper Library" or "Universal Termsrv.dll Patch" executables automate the process. However, these tools are frequently flagged by antivirus software and may contain malware if downloaded from untrusted sources.

RDP Wrapper uses API hooking and memory patching techniques to intercept function calls to the Terminal Services licensing components. It then applies runtime modifications to change the file's default behavior and bypass the session limit without permanently altering the DLL on disk. The tool uses a configuration file ( rdpwrap.ini ) that contains version‑specific memory offsets and patch instructions for different Windows builds. For Windows Server 2012 R2, this configuration can be updated to support new termsrv.dll versions as they are released. RDP Wrapper is widely considered the safer and
