windows 10 - query session command gives error code 5 even when AllowRemoteRPC is set to 1

in cmd, 'Query Session' command is returning,

Error 5 getting sessionnames
Error [5]:Access is denied

on Windows 10 Remote desktop - Administrator user.

we have set, AllowRemoteRPC 's value to 1

under this HKLM\SYSTEM\CurrentControlSet\Control\Terminal Server

But still problem persists.

Questions:

• what does AllowRemoteRPC actually do and how it's value is being used.


• what to do to make Query Session command work.

Answer

I think the problem is in the UAC remote restrictions.

Do this on the target computer:

• Run regedit


• 
  

  Navigate to the following registry subkey:

  
  

  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
  



• 
  

  If an entry named LocalAccountTokenFilterPolicy registry entry does not exist, create it as DWORD

  
  


• 
  

  Double-click LocalAccountTokenFilterPolicy and set its value to 1.
