Enable RemoteApp

[aiugrivef]

Hello,

I can see in your code that you change some variables for RemoteApp, so I tested RemoteApp on Windows 7 Pro x86 (6.1.7601.18637).
However, this is not working at all.

Full Desktop remote sessions are working fine, but RemoteApp not.
Do you have any idea on how this could work ?

Also, do you know how to activate Debug Messages for termsrv.dll ? I wanted to help you, but I cannot see these Debug Messages with WinDbg...

Well, RDP Wrapper doesn't provide RemoteApp features officially.

If you're wondering about "TerminalServices-RemoteConnectionManager-AllowAppServerMode" policy value, I don't know how it will work in non-server editions.

So actually it's not an issue.

About Debug Messages, you can try to intercept that function to catch text messages into log file. I tried to do that but the function differs between termsrv releases. To turn it on without hacks, maybe you need to boot Windows in debug mode and attach it to WinDbg.

Also I updated config file, added more policy values:
https://github.com/binarymaster/rdpwrap/blob/master/res/rdpwrap.ini

Just replace old INI file and restart TermService. Maybe it will help.

And you may try this app:

Some users told that it works with RDP Wrapper, see posts #141 and #145:

Hello,

Thank you for your help. As said on DigitalLife forums, RemoteApp is working fine with W7 Ultimate, however it is not working wit Win 7 Pro (or lower edition).

By trial and error I can go to these errors in termsrv.dll:
GetInstanceOfRemoteConnectionManager
CConnectionEx::ProcessData
FindConnectionHandler failed: 0x800710d8 in CRCMConnDispatchManager::HandleConnection

Maybe this could help you?

I researched a bit these things...

RemoteApp requires these files:
%SystemRoot%\system32\rdpinit.exe
%SystemRoot%\system32\rdpshell.exe
%SystemRoot%\system32\TSErrRedir.dll
%SystemRoot%\system32\tspubwmi.dll
%SystemRoot%\system32\wbem\tsallow.mof
%SystemRoot%\system32\spp\tokens\ppdlic\terminalservices-remoteapplications-clientsku-ppdlic.xrm-ms

tspubwmi.dll can be installed via RegSvr32
tsallow.mof can be installed via mofcomp

Also rdpinit.exe requires TerminalServices-RemoteApplications-ClientSku-RAILAllowed policy

I tried to install it but however not succeeded.

Also tried to import this registry key:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\TerminalTypes\eddcc3ce-6e7e-4f4b-8439-3d9ad4c9440f]
"Name"="Remote Applications Terminal"
"SessionSource"=dword:00000001

...still no success
I only know that the "problem" is somewhere inside termsrv.dll

[binarymaster]

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\ConnectionHandler\eddcc3ce-6e7e-4f4b-8439-3d9ad4c9440f]
"CLSID"="2be8bdbb-be09-499d-9a4b-4637e09ae00b"
"Description"="Default Connection Handler"
"Name"="Default Connection Handler"
"fAcceptConnection"=dword:00000001

Adding this registry key helped me to get a new session when connecting in RemoteApp mode.
But rdpinit.exe was not started and session closed immediately.

Hello,

Thank you for your time. I will put another program as rdpinit.exe and/or use the Win 7 Ultimate edition.
For me, you can close this issue.

Out of curiosity, how did you find those registry keys? Are they somewhere in termsrv.dll ?

Thank you again!

[binarymaster]

First of all I compared "Terminal Server" registry keys between Professional and Ultimate editions.

Also I researched these updates:

• KB961742 (turns on RemoteApp on Windows XP)
• KB961741 (on Windows Vista)

Ok. Feel free to reopen this issue if needed.

I'm also having some RemoteApp issues with Windows 10 TP2 build 9926. Before the update I was staying with 9874 and everything runs smoothly. Now RemoteApp refuses to start initially, but once a full rdp session is established, it restores functionality. Maybe, I guess they have brought in yet another jmp instruction for us to patch under certain circumstances.. :-D

Enable RDP -> Programs -> "Start the following program on conection"

Regedit:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services]
"fAllowUnlistedRemotePrograms"=dword:00000001
;"fTurnOffSingleAppMode"=dword:00000000
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server\TSAppAllowList]
"HonorLegacySettings"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server]
"HonorLegacySettings"=dword:00000001

binarymaster, except all things that you mentioned, you have to patch rdpinit.exe (1.7601.17514) with following:
0000568E: 04 01
0000568F: 40 00
00005691: 80 00
This is return value of checking ...ClientSku-RAILAllowed policy. Assuming that policy is missing.
