Hi there!
So we’ve encountered issues in the past related to RDP allowing certain PS elements to work.
Basically, RDP just do happens to start a few services that Windows needs to play media, that wouldn’t otherwise have started. For instance the Audiosrv service was necessary in some cases.
If you wanted to confirm which services are being started with an RDP connection you can do the following:
RDP in and look at services.msc to see which services are active.
Restart, then SSH in and do the same, avoiding RDP.
In Powershell, you can run Get-Service | Where-Object { $_.Status -eq ‘Running’ } in order to check the running services (this will thankfully work with both RDP and SSH)
You’ll be able to compare the 2 results and see which services are starting with RDP.
As a solid starting point, try Set-Service -Name Audiosrv -StartupType Automatic
I recall that without this service, video playback will fail if the video has audio.
Let me know if this gets things moving for you, otherwise we can look into it further!
