Windows 10 Remote Desktop Not Listening

[megatc101]

Hi

As this is my first post of 2020, let me wish you all a happy new year.

So down to business

Does anyone have a fix for windows 10 Remote Desktop not listening on port 3389.

I recently rebooted my admin windows VM only to find that I could not reconnect. This VM is running 1903, the last patch is KB4530684, which is a cumulative update, that was installed on the 2nd January 2020.

I can confirm that Remote Desktop is enabled

I've copied termsrv.dll from a working VM, this has not made any difference.

What is annoying is that this is the second time that I've encountered this problem, for the other VM I relented and did a recovery/reset, this fixed the problem, but them there is the issue of having to re-install all the applications, as this is a management VM used by admins, having to re-install all of the admin software is going to be a pain.

I'm therefore reaching out prior to doing another recovery/reset in the hope that someone has a fix.(the font has changed to this???)

It seems there was a similar issue with Windows 1809, for which Microsoft released a patch, I'm assuming that, that patch is incorporated into the 1903 cumulative update.

Here are the things that I've checked

The service is running

PS C:\WINDOWS\system32> Get-Service "*term*"


Status Name DisplayName
------ ---- -----------
Running TermService Remote Desktop Services


However nothing is listening on port 3389 ( here is a partial netstat -an)

PS C:\WINDOWS\system32> netstat -an

PS C:\WINDOWS\system32>

This is not a firewall issue.

I've checked the registry and the settings are all as expected (see below)
