I have a small network with Windows-7 computers and one running Windows-8.
How can I remotely shutdown the Windows-8 computer ?

I am used to run cmd: shutdown /s /m \\<computername>

even when I right click cmd and Run as administrator, my Windows-7 computers
gets access denied (5)

All computers have the same Username and password, including administrator.
I enabled the policy to prevent 'Force Shutdown From A Remote Machine'. in SECPOL on the Windows-8 machine.

How can that be solved ? without setting up a RDP session.

Can you ping and access the C$ share of those windows 8 machines?  It sounds like there is an issue with communicating with the machine....maybe policy related if its not accoun

Hi,

Please ensure the account is in Administrators group. You can refer to this post.

thanks Chris, Niki,

My account is in the admin group but could not access \\<WIN-8 computer>\C$

using "administrator" did the trick.
