How to Enable Concurrent Users/Sessions in Windows Vista

Posted in Microsoft, Vista, Windows Media Center by amonteiro on March 13, 2007

My MCE computer is used completely for home theater purposes, and so it is very rarely used outside of the MCE environment. It also does not have a keyboard and mouse hooked up to it. This makes it very hard to accomplish any maintenance tasks without using remote desktop.

Unfortunately, by default Vista does not allow concurrent users logging in at the same time. So, until recently, if I wanted to rearrange some files on the computer, I would have to log in using remote desktop (which logs out the MCE user), rearrange the files, log out, connect a keyboard to the MCE computer so I can enter the password, and re-login with the MCE user.

Fortunately, the relentless folks at The Green Button have put in a lot of effort to find a work around. After some clever hacking you can log on with multiple users to the same Vista machine. Here is a link to the discussion so you can see the progress they have made.

And finally a how to taken from Missing Remote

  1. Download Sunmorgus’ hacked Termsrv.dll file HERE (If you’re using Vista HOME PREMIUM, use this link and follow the reg instructions below.)
  2. Now, Vista’s security needs a little massaging to allow you to modify the original termsrv.dll file, found in C:\Windows\System32, so….
  3. Click Start, then type “cmd” in the search box & hit enter. This will launch the Command prompt
  4. Type the following & hit enter: takeown /f C:\Windows\System32\termsrv.dll
  5. Then type this & hit enter (NOTE: Replace USERNAME with YOUR USERNAME!! If your name has a space in it, enclose it with quotes, like “Mike Garcen”): cacls C:\Windows\System32\termsrv.dll /G USERNAME:F
  6. Then go to your Windows Explorer, and go to C:\Windows\System32
  7. Rename the original termsrv.dll to something else, like “termsrv.dll.ORIGINAL”, just in case
  8. *NOTE* If you are unable to do the above, try rebooting into SAFE MODE
  9. Then copy & paste the Hacked DLL you downloaded in Step 1 into the C:\Windows\System32 folder
  10. And voila!

    The link you’ve provided for the Termsrv.dll is dead (404).
    Do you have another url?

    Cheers

    I may be missing something here, but the ‘takedown’ command is not recognized as a valid command in Vista (or at least, in Home Premium). So, I get stuck when I try to type ‘takeown /f C:\Windows\System32\termsrv.dll’ in cmd.

    Error Message:
    ‘takedown’ is not recognized as an internal or external command, operable program or batch file.

    Any ideas?

      just run it as an administrator after you find it right click and select that option

    can someone please confirm that it works on SP1? I’m using Vista Ultimate x64 SP1…

    This fix .. ie the “takeown” method did not work.

    Microsoft’s website doesn’t even acknowledge the problem and I’ve seen it on three machines now.

    Any help would be appreciated.

    This isn’t a “fix” it’s a hack meaning Microsoft won’t acknowledge it. The takeown command line function is only available on Vista Business and Ultimate. There are other procedures for Vista Home Premium on the green button web site mentioned above.

    I’m running vista business sp1 x64 and can not get this to work. I’ve downloaded the 32 and 64 bit versions. The 64 bit version seems to run but I can not remote in. When I revert back to the original dll the remote desktop works normally.

    Anyone else got this to work on x64 business sp1?

  12. Gizz said, on February 5, 2009 at 3:32 am

    just to make it a bit more complete (for Ian), you should run takeown as an administrator, so run cmd as an admin.
