    Hi,
    pretty new RAS Admin here.

    Just updated to version 20.2 from version 19 and not quite sure if this is something related to that, but it seems that I am not able to use the Disable Logons from the RD Session host management anymore. It says that "cannot change because... server's group policy". But I checked that the policy is in "Not configured" state.

    I also checked this kb https://kb.parallels.com/130953/
    And that asks to delete the key: fDenyTSConnections from HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Terminal Services but there is no such key.

    I did find that this key does exist in: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server
    Didn't get the chance to test if deleting the key from here helps, but just something I am wondering about. Will update once I can test this.

    I had that error earlier and I had the key. Once deleted in my template and re-apply to my target VM it work.

    If Disable logons is not working, it's usually due to one of these reasons:

    • Policy not applied to the correct OU

    • Conflicting GPO overriding the setting

    • Using the wrong option (e.g., Deny log on locally vs Deny log on through RDP)

    • Group Policy not refreshed or user already logged in

    • Cached credentials allowing access
    Quick check:
    Run gpresult /r or rsop.msc, then log off/reboot and test again.

    If it still fails, verify the logon type and where the policy is applied.
