Customer Advisory: (Resolved) Login Screen Freezing on Windows 11 Version 24H2

Problem

Users have reported issues with Workspot sessions appearing to hang or freeze during login after updating their Workspot Desktops to Windows 11 version 24H2. This document provides solutions to fix login issue.

Cause

Microsoft reports that this is a known issue introduced in KB5050094 in January, 2025.

Resolution

This is fixed in Microsoft’s Windows 11 Version 24H2 2025-03 Cumulative Update Preview KB5052093 (OS Build 26100.3323) from February 25, 2025. Install this update (if it hasn’t been installed automatically) to resolve the issue.

Workarounds

Note: These workarounds are now obsolete but are kept for completeness.

Option 1: Applying Group Policy

This works around the problem by altering server-side RDP settings. It would normally be set on the domain controller and be pushed to the target desktops, but can be set locally in the Workspot template or desktop VMs.

This configuration tells the operating system not to continuously probe for network changes when reconnecting an RDP session, thereby addressing the hanging issue.

You can implement these changes via the Group Policy Editor or the cmd command line.

This solution restores connectivity but the “Connection Health” display will show a poor status continuously, regardless of the actual connection health:

User interface showing connection options, keyboard shortcut, and settings menu.

Using Group Policy Editor

Press Win + R, type gpedit.msc, and press Enter to open the Local Group Policy Editor.

Navigate to “Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Connections.”

Double-click on "Select network detection on the server".

Set this policy to "Enabled", and under Options, choose "Turn off Connect Time Detect and Continuous Network Detect".

Click "Apply" and "OK".
Open a Command Prompt as an administrator and run the command gpupdate /force to apply the changes.

Settings for network detection on the server, including enabling and disabling options.

Using the Command Line

Open Command Prompt as an administrator and run the command:

reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v SelectNetworkDetect /t REG_DWORD /d 3 /f

Run the command gpupdate /force to apply the changes.

Option 2: Registry Edit

This option disables the problematic network monitoring features.

Open command prompt with elevated privilege.

Run the following commands to add registry settings:

reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v fServerNetworkDetect /t REG_DWORD /d 1 /f
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v fTurnOffTimeDetect /t REG_DWORD /d 1 /f
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services" /v fTurnOffNetworkDetect /t REG_DWORD /d 1 /f

This will make the following changes:
- fServerNetworkDetect = 1, network detection is enabled at the system level, but since the other two policies (fTurnOffTimeDetect & fTurnOffNetworkDetect) disable connection monitoring, RDP won’t respond to network fluctuations.
- fTurnOffNetworkDetect = 1, the Continuous Network Detection feature is disabled.
- fTurnOffTimeDetect = 1, the Connect Time Detect feature is disabled.

To validate, Open Registry editor and navigate to

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services

Reboot the Virtual Desktop and connect to the Workspot Client.
