Windows Server 2022 App Compatibility FOD breaks Remote Desktop

[mauricewalker]

When installing the App Compatibility FOD on Windows Server 2022, Remote Desktop connections to the server seem to be no longer possible. I think this is a bug, but haven't found any other reports. Can someone confirm?

How to reproduce:

• Install Windows Server 2022 Standard Core (physical and virtual installs are equally affected).
• In SConfig, enable Remote Desktop.
• Connect to the server via Remote Desktop using the default 'Administrator' account. Works fine.
• Install the App Compatibility FOD and reboot:

Add-WindowsCapability -Online -Name ServerCore.AppCompatibility~~~~0.0.1.0
Restart-Computer

• Try establishing a Remote Desktop connection again. Doesn't work. You either get a blank screen or get disconnected immediately.
• Install all applicable Windows Updates and try again. No change.
• Remove the App Compatibility FOD and reboot:

Remove-WindowsCapability -Online -Name ServerCore.AppCompatibility~~~~0.0.1.0
Restart-Computer​

• Try again. Remote Desktop functionality is now restored.

This did work fine in Server 2019.

@mauricewalker 

I have the same issue and didn't find any solution yet

[#3]

Same here.

Using windows admin center to remote manage but sometimes you still need RDP.

Thanks for confirming. Hard to believe no-one at Microsoft noticed this. Without RDP, the App Compatibility FOD is pretty much useless, isn't it?
WAC is also my preferred management tool, but it's still missing some Hyper-V features (like attaching physical disks to a VM). So I would like to use the Hyper-V Manager (virtmgmt.msc) via RDP.
What's the best way to escalate this?

[#5]

Because it's not a preview issue I'm not sure we can raise it via insiders. I did see the FOD install are currently broken in WinSvr vNext so perhaps this will get fixed when they re release it?

I will also try and raise this via my MS account team at work...

[#6]

I'm running the release version and the issue is present. I'm waiting for an update that could fix it

[#7]

I've been told by MS to log it in the feedback hub on a win10 or win 11 machine. I've done that so would be good for people to up vote.

I just noticed that the Devices Tool in Windows Admin Center shows a "Critical" device while trying to establish an RDP connection:

SWD\REMOTEDISPLAYENUM\RDPIDD_INDIRECTDISPLAY&SESSIONID_0002
The drivers for this device are not installed. (Code 28)

Hi,
I do not have any unknown devices when attempting to connect via RDP. It passes auth but then there is something not being invoked. I suspect it's graphics driver related, but not sure why FOD would alter that! I've done everything from re-install graphics drivers, to reverting to the windows basic driver to disable Bitmap Caching, RemoteFX etc. Still no joy 😞

[#10]

Same for me, tried several installs on different machines with different GPUs and drivers because I initially thought it might be a graphics driver issue. But I'm now pretty confident it isn't.
I've given up for now and use WAC plus local KVM when absolutely necessary. Hoping for a timely patch.

Hey @JOHNPILLAR, I just installed Feedback Hub to upvote the issue. But this seems to be just a steaming pile of rants about Facebook being broken and other nonsense. I was unable to locate your bug report. Could you post a link (if that's a possibility with Feedback Hub) or some keywords? I tried the obvious ones.

Title: Windows Server 2022 - App Compatibility FOD breaks Remote Desktop (RDP)

I used your well explained steps to re-produce, hope that was ok.

[#13]

Thx, upvoted yesterday.

[#14]

@JOHNPILLAR, the link doesn't work for me. Feedback Hub says: "Your account doesn't have access to this feedback". Is this for Insiders only?

[#15]

Oh, there should be no restrictions on it. I did not set any so must be a MS thing.

[#16]

@mauricewalker with my work Account i also have no access to this feedback...

[#17]

Upvoted as well - since apparently uservoice doesn't exist anymore - would love to know how this hit GA.

[#18]

I have the same problem without a server core. Any news?

[#19]

same. rdp not working.
but in version with no graph interface it works.

[#20]

@sysadminRiga thanks and interesting. Can you share install params/changes to any settings etc.

Thanks
