If you are having constant disconnection and re-connection messages when connected to a Remote Desktop RDP Server that occur frequently in less than 5 minute intervals.

Where you briefly see the following message then get your session back again.

 

 

 

 

 

 

 

 

You can on your client which is connecting to a Remote Desktop server make the following registry change.  This change makes the Remote Desktop client use a TCP connection instead of a UDP connection.  This will not affect any other features of the Remote Desktop client or its capabilities or settings to connect to your host.

On the client computer connecting to the Remote Desktop host, add this DWORD entry.  Be careful modifying the Registry incorrect changes to the Registry can stop your computer from working.

Open Regedit
In the following Key – [HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client]
Add a DWORD (32-bit) Value – fClientDisableUDP
Double click your new entry and set it to 1, changing the 0 to 1

Now your remote desktop sessions should stay connected, until Microsoft fixes this problem then you can remove this DWORD value, although there is nothing wrong with keeping it set to use only TCP.
