Windows 11 22H2 RDP disconnects and freezes randomly

-

Namaste Everyone.

I have been following and reading many forums with the similar issue of RDP session freezing or either getting disconnected frequently. Logs have not proved anything exceptional or drastic changes in the environment, however I was able to test this in my lab and have traced some Network Logs via the Wireshark and could see retransmision packets between the client and the server. This all started after the update to Windows 11 22H2.



The resolution is to either rollback the 22H2 on the client or apply this registry or ADMX setting via the Group Policy.

My theory is that after looking at the logs in my client is that the problem is due to the fact that the RDS connection is trying to connect over UDP and is not trying to connect over TCP if the UDP fails or gets block for some reason.

So either you can manually set the registry in the client by following the below step:

Browse to the below Registry Path with administrator account:

HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client
Create a DWORD named fClientDisableUDP and assign it a value of 1
Reboot the client PC.

or via GPO ADMX follow this link to browse the GPO settings. Visit the ADMX page over here.

Hope this helps and you are able to have a steady connection to the RDP server.

    Is it possible the remote session gets killed by a lack of mouse movement with Win 11?

      If there are some policies on the server RDP and timeout values are set to disconnect idle sessions.

    this worked for me on the Host side: gpedit.msc > Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Select RDP Transport protocol > Set enabled and choose TCP only, Reboot.

    It worked for me, now it disconnects gracefully and reconnects automatically, instead of just going unresponsive.

 Namaste everyone, During the install of a new Azure AD Connect software I was provided a brand new Windows 2019 Server Datacenter Edition and this was fully patched and updated with the Security patches. There were no Group Policies with exception of the Domain Policy and a SCCM Server Policy for patching. I noticed the time was out of sync an hour as the server was located in the different region and all other servers were set to local region settings. So the usual step is to try and change the date and time from the Control Panel, however when I tried to update the time I received a message that I cannot change the time. "Unable to continue" You Do not have permissions to perform this task. Please contact your administrator for help. The simple fix to use the Get-Timezone and Set-Timezone PowerShell commands,  Get-TimeZone -ListAvailable | where StandardName -like "*GM*"    ( This command will extract the specific Timezone with the words GM in the StandardName, y...
