Publish RemoteApp on RDS Without Domain

On an RDS host in a workgroup, the session management console is not available, so there are no tools to publish RemoteApp. There is a workaround that allows you to publish any application as an RDS RemoteApp without an Active Directory domain.

Example REG file for publishing AdobeReader as a RemoteApp on the RDS session host:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Terminal Server\TSAppAllowList\Applications\MyAdobeReaderApp]
"CommandLineSetting"=dword:00000000
"RequiredCommandLine"=""
"Name"="Adobe Reader"
"Path"="C:\\Program Files\\Adobe\\Acrobat DC\\Acrobat\\Acrobat.exe"
"ShortPath"="C:\\PROGRA~1\\Adobe\\Acrobat DC\\Acrobat\\Acrobat.exe"
"IconPath"="C:\\PROGRA~1\\Adobe\\Acrobat DC\\Acrobat\\Acrobat.exe"
"IconIndex"=dword:00000000
"ShowInTSWA"=dword:00000001
"SecurityDescriptor"=""

Replace the app name and paths in the REG file with yours and import it into the RDSH registry.

To automatically launch the published RemtoteApp, manually edit the *.RDP file. Add the following lines to the RDP file:

remoteapplicationmode:i:1
alternate shell:s:||MyAdobeReaderApp
remoteapplicationname:s:MyAdobeReaderApp
remoteapplicationprogram:s:||MyAdobeReaderApp

Try to run a RemoteApp application on the RDS by using your RDP file. The application published on RDSH should launch successfully on your desktop.
