Hello,

Am Kalasagar

Dear Microsoft Support Team,

I hope this message finds you well. I have encountered an issue while configuring the remote desktop settings in. Specifically, the option "Allow connections only from computers with network level authentication" is greyed out and inaccessible.

I have reviewed the documentation and user guides, but I could not find a solution to enable this option. As a result, I am unable to enforce network level authentication for remote desktop connections.

Could you please provide guidance on how to enable or activate the "Allow connections only from computers with network level authentication" option? I want to ensure secure remote desktop access to my system, and this feature is essential for achieving that.

I appreciate your assistance in resolving this matter. If there are any specific steps or requirements I need to fulfil to enable this option, kindly let me know. Any additional information or resources you can provide to address this issue would be greatly appreciated.

Thank you for your time and support. I look forward to your prompt response.

Best regards,

R Kalasagar

    Hello,

    Thanks for reaching out! I'm Microsoft user like you.

    I assume you are Local Admin on this Computer

    Go to Start -> Run -> Type gpedit.msc then Press Enter

    This is in Group Policy, in Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Security. The policy is "Require user authentication for remote connections by using Network Level Authentication" -> Enable it.

    Best Regards,

    Prakash

    after setting or ensuring that the aforementioned registry keys were in place, rebooting the server, the checkbox for NLA is still greyed out.

    any suggestions?

    Have the same issue. Try all the above doesn't work.

    I compared the registry key of 2 different servers (1 greyed out & 1 no greyed out).

    Found that the one that greyed out got an extra registry key. I deleted it & it works. No Need to restart the server.

    Delete UserAuthentication from

    HKLM\Software\Polices\Microsoft\WindowsNT\TerminalServices

    Hope this solve your issue too.

    For the "Allow connections only from computers with network level authentication" grayed out issue follow the below steps:

    1. gpedit.msc - Computer Configuration -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Security. The policy is "Require user authentication for remote connections by using Network Level Authentication" (Enable that option)
    2. Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services -fdenyTSconnections value is 0. (if it is 1 change it to 0).
    3. HKLM\Software\Polices\Microsoft\WindowsNT\TerminalServices (if it is 0 change it to 1) in registry editor go to view tab and refresh it. (I don't think deletion is required here)

    The option is now enabled, and for regedit changes no reboot is necessary.

    Also try set this parameter in here then it will work:

    Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services -fdenyTSconnections value is 0.
