Enable RDP to take remote of Intune managed devices, Firewall blocking the connection

Hi Deleted 

I was suggesting using the new Firewall Rules in Endpoint Security, https://endpoint.microsoft.com/#view/Microsoft_Intune_Workflows/SecurityManagementMenu/~/firewall.  Create New Profile Windows 10/11 - Microsoft Defender Firewall Rule - Edit Rule - Then Apply the Settings below and test. 

How did you confirm the issue from Windows firewall? Are your devices Azure AD Joined? Have you enabled the remote setting setting under Setting - System - Remote Desktop? I was prompted to enter creds without firewall policy as soon as I enabled the setting. You may need that setting only.

It will be great if you send us screenshot of the error you seeing.
