    I think, at all need to replace 3 things:
    007444833D46BA<=>00EB44833D46BA
    EC2033DBC7400801<=>EC2033DBC7400800
    39813C0600000F84D9510100<=>B80001000089813806000090

    Tell me if it works :)

    I can no longer establish a rdp connection to the virtual machine which I use to test this. Also the console connection is no longer working.

    Look's good. I'm not shure, do you make any registry editions...
    May be you can change just one

    - There are some very old GPOs which were working for over a decade.

    HKLM

    SYSTEM\ControlSet001\Control\Terminal Server\Licensing Core
    EnableConcurrentSessions = 1

    SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
    EnableConcurrentSessions = 1

    SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
    AllowMultipleTSSessions = 1​


    - I have tried to change only the first Bytes, again. This was my very first try :) but... no success!
    - Now I have removed the three GPOs, but it is still not working.

    Thanks a lot for your time!

    I am doing this for over a decade, always the same procedure. I will test to restart the PC, maybe this is a new requirement in 2004, to restart the PC after replacing the DLL, instead of restarting the services only. I will report.

    how stupid this is... I was needed to restart the virtual machine twice after applying the patch. Now it seems to work, but not before the restart.

    Thank you!

    19624? First of all, that's a fast ring build. Second, it's not even the current one but two out of date. Third, even if it were the current one, there's about a 75% chance that it wouldn't be by later this afternoon. Short version: you're unlikely to find patches for moving targets like that here.

    On my github rdpwrapper works perfect. If you don't want to use it and want to patch termsrv.dll - you can use information from my rdwrap.ini, as i provide on a previous page
