every 30 min user gets disconnected w/ error ConnectionBrokenMissedHeartbeatThresholdExceeded

chrisp1992 I had 3 users last week with a similar issue. This is what I checked:

• The user's internet speed
• The connection information on the Remote Desktop Client
  • If the transport protocol is UDP, this is where I think the issues persist
  • If it does not say UDP, you may have to contact support to further investigate

The fix I did:

In my company domain's group policy, I changed 2 settings:

• Under Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Connections select Select RDP transport protocols, enable it, and choose Use only TCP
• Under Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Connection Client select Turn Off UDP on Client and Enable it

Reboot the user's instance through Intune, Unsubscribe from their client, reboot the user's endpoint so they can have a fresh login, and subscribe again. This has worked for my users as they have been up and running for about a week now.

If you need to have UDP enabled through company policy, {I havent tried this yet} there is a registry key that you will need to insert under the user's endpoint.

REG ADD "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services\Client" /v fClientDisableUDP /t REG_DWORD /d 1 /f

Then try the refresh steps above and see if that works.

Hopefully this helps!!
