If you ever get this in Windows 7
Logon Message:
Another user is currently logged to this computer. If you continue, this has to disconnect from this computer. Do you wish to continue ?
That’s because Windows 7 by default don’t allow concurrent user access. If either the RDP session user or the host user try to login, the other people will not be able to login while there is already a user. So you will get this message when you try to RDP a Windows 7 machine.
But there are ways around this. Basically all you need is to replace the termsrv.dll file in the %SystemRoot%\System32\termsrv.dll
You can download the termsrv.dll here
Run the install batch file. and If you are not running RC change this line in the batch file to match your version number.
However, the batch file didn’t not install it correctly for me, so I have to manually replace the termsrv.dll file in the directory.
If you are running 64 bit OS make sure to replace the 64 bit one.
Once this is done you should be able to see multiple users in the Task Manager > Users Tab
