Windows 11 has a significant issue affecting Remote Desktop Protocol (RDP) sessions during the login phase, potentially linked to the Windows 11 24H2 update or recent security updates KB5050094 and KB5051987. Administrators have reported difficulties in establishing RDP connections since the rollout of the 24H2 update, with issues persisting even when the RDP service is operational and firewall configurations are correct. Users have noted that changing the default RDP port from 3389 may resolve connection issues for some, although this workaround is not universally effective. Additionally, there are reports of RDP sessions hanging during the login process, particularly when reconnecting to previously disconnected sessions.
To address the hanging issue, users can modify settings in the Group Policy Editor by enabling the "Select network detection on the server" policy and turning off Connect Time Detect and Continuous Network Detect. A system reboot is not necessary, but executing the gpupdate /force command is recommended. Alternatively, a Windows Registry script can be used to automate the process across multiple devices. As of February 21, Microsoft has not officially acknowledged these network issues, despite their widespread impact on users.
