windows powershell

ps c:\users\administrator> get-itemproperty -path 'hklm:\system\currentcontrolset\control\terminal server'-name "fdenyt
connections"
fdenytsconnections : 0
pspath             : microsoft.powershell.core\registry::hkey_local_machine\system\currentcontrolset\control\terminal s
                     erver
psparentpath       : microsoft.powershell.core\registry::hkey_local_machine\system\currentcontrolset\control
pschildname        : terminal server
psdrive            : hklm
psprovider         : microsoft.powershell.core\registry

ps c:\users\administrator> get-itemproperty -path 'hklm:\system\currentcontrolset\control\terminal server\winstations\r
p-tcp' -name "userauthentication"

userauthentication : 0
pspath             : microsoft.powershell.core\registry::hkey_local_machine\system\currentcontrolset\control\terminal s
                     erver\winstations\rdp-tcp
psparentpath       : microsoft.powershell.core\registry::hkey_local_machine\system\currentcontrolset\control\terminal s
                     erver\winstations
pschildname        : rdp-tcp
psdrive            : hklm
psprovider         : microsoft.powershell.core\registry

ps c:\users\administrator> get-netfirewallrule -displaygroup "remote desktop" | format-table name, enabled -autosize

name                          enabled
----                          -------
remotedesktop-usermode-in-tcp    true
remotedesktop-usermode-in-udp    true

so seems correct.

i not have installed remote desktop server/services etc. because ther no need to.

i did not change on host, no updates etc short before problem occurred. not on clients

where find solution. on internet not find it, checked.
