Why is the network access denied?

Question

Computer networks

Hello. There is a laptop with Windows 10 and a desktop with Windows 7. They are on the same network. Through a router. Everything is set. They ping each other.
I give a command from the laptop to turn off the stationary one, and it says "Access denied (5)" I
set up local policies so that everyone could be cut down remotely.
What could be?

Answer 1

I suppose this is to blame: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\LocalAccountTokenFilterPolicy
This parameter should be set to 1. If it is not there, then create a DWORD type.
This UAC is naughty - the operation requires administrator privileges, and over the network you will not be able to elevate privileges.
This setting allows network communications to override UAC, i.e. if you logged in with administrator rights over the network, you will have administrator access without the need to elevate privileges.

Try to check before that that you can connect to the computer via
net use \\IP address\IPC$
if you get an error, then this is the problem, try to connect anonymously
net use \\IP address\IPC$ "" /u:""
or specifying the account login/password on the target computer
net use \\IP address\IPC$ /user:USER_NAME
