Windows Professional and Ultimate editions come with a built in Remote Desktop feature that allows you to access your machine remotely while you are away from home or the office. Unfortunately, it’s limited by default to only one concurrent user per one session, it’s meaning that if someone remotely connect to the computer, anyone who was logged in at the moment will be automatically logged off, even when the user is physically at the computer.
This is not a technical limitation but rather a licensing one. Case in point, Remote Desktop in server editions of Windows by default supports two concurrent connections to remotely troubleshoot or administer a computer. More users can connect simultaneously, too, as long as the machine can handle it with the resources it has available and you have the required client access licenses for that particular server.
However, there are a few reasons why concurrent sessions would come in handy for power users not necessarily running a server. For example, if you have a dedicated Media Center PC running in the living room, you’ll be able to remotely access all files on the machine without interrupting the person watching TV.
Or if you are sharing a computer with other users, concurrent Remote Desktop sessions will allow more than one person use that system under a different or even the same user account, without kicking each other off. By patching a file called termsrv.dll, located in %SystemRoot%\System32\, this is possible in all editions of Windows 7, Windows Vista and Windows XP.
1. UniversalTermsrvPatch_20090425 (download here)
1. Download the patch from the link above and run it using administration rights.
2. After that a new window will show up. There’s a button to patch your Termserv.dll to make it accept concurrent remote desktop session.
3. When you click the patch button, a pop up will appear, told you that the patch applied successfully.
4. I’ve try to connect 2 users (windows 7 and backtrack 5 r3) using remote desktop and 1 users active on the desktop (total 3 users). here’s the screenshot.
5. The active user was not logging out even there’s another user connected to its using the remote desktop.
