I am encountering an issue with remotely shutting down PC’s on my home network. My laptop (MY-PC) is on HOME WORKGROUP and can remotely shut down my other laptop (MY-PC2) which is on a work domain. However it does not work the other way round. Neither of these two laptops can shut down the desktop (STUDY-PC), also on HOME WORKGROUP. Errors are always returning “Access denied (5)” despite my network having all sufficient permissions and all computers logged in to the network and locally as admins. I am using the cmd “shutdown -m \\computername -t (time) -s” and returns the error. If I try to use the “runas user:/computername\username” it will ask for the passwords but dismisses it as being invalid credentials.
MY-PC is running Windows 7 Home Premium
STUDY-PC is running Windows XP Home Edition
MY-PC2 is running Windows 8.1 Pro
None of the solutions on Google work for me. Please help! Huge thanks to anyone who solves it or at least offers a suggestion.
