Windows 11 Pro Remote Desktop Connection to a Windows 2012 Server disconnects after a few seconds

I have a Windows 11 Pro PC running 24H2 and whenever I use Remote Desktop connection to connect to a Windows 2012 server, the session disconnects after a few seconds after connecting perfectly fine. I have another PC running the exact same version of windows and with using the same credentials, the RDP session from that PC connects and stays connected. So because of this I have ruled out the server and network and have been comparing both PCs to see if there are any differences in the configuration but everything is the same so far. Need help.

    Dear JASON VEIRA,

    Recent updates to Windows 11 24H2 have introduced changes to how RDP handles transport protocols. In some cases, the use of UDP (User Datagram Protocol) for RDP connections can cause instability or premature disconnections when connecting to older servers such as Windows Server 2012.

    Here are Recommended Resolution

    To resolve this issue, we suggest forcing the RDP client to use TCP only, which has proven effective in similar scenarios.

    Option 1: Modify Group Policy (Recommended for Domain-Joined PCs)

    1. Press Win + R, type gpedit.msc, and press Enter

    Navigate to: Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client

    Enable the policy: "Turn off UDP on client"

    Apply changes and restart the PC

    Option 2: Registry Edit (For Non-Domain PCs)

    Open Registry Editor (regedit)

    Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client

    Create a new DWORD (32-bit) value named: fClientDisableUDP

    Set its value to 1

    Restart the PC

    This change will force the RDP client to use TCP only, which improves compatibility with older servers and resolves the disconnection issue. Ensure both PCs are running the same cumulative updates, as patch levels may affect RDP behavior.

    I hope this helps. Just kindly tick Accept Answer that others in the community facing similar issues can easily find the solution. Your contribution is highly appreciated.

    The recommended change was made but did not resolve the issue unfortunately. Any other suggestions?
