Windows – Remote machine closes automatically

rdpwindows

Recently I am facing an issue in Windows Remote Desktop access.

I was able to connect to the machine without any problem till yesterday.

Today, I have opened Remote Desktop Connection and credential popup opened.

I have entered my credential as usual. Once I pressed enter, credentials validated and while entering into machine, it closes automatically.

After some time it shows a dialog with the error message:

Because of a protocol error (code: 0x112f), the remote session will be disconnected.

What is the the problem and how can I solve it?

This error may be triggered by insufficient memory on RDP server. Try to restart server.

A little known one is

getmac

It shows the MAC address(es) of your network adapter(s).

Screenshot of running getmac from a Windows commandline window.

This problem may occur due to low memory on the remote server.

For me, doing the following fixed the problem:

Go to the Experience tab, and disable the following:
- Desktop Composition
- Visual Styles
- Persistent bitmap caching
Go to the Display tab:
- Set a smaller resolution
- Lower the color depth (for example 15 bit)
Also, if you don't need the remote audio, go to Local Resources tab:
- Click the Remote audio -> Settings..., check Do not play and Do not record

No need to change the RDP Compression from the Group Policy on the remote machine, only disabling these should do the trick.

Tested to work on Windows Server 2008 R2 SP1 as the remote, and Windows 10 Pro as the client.
