Hi,
Thank you for posting your query. According to your description, you are intended to remotely shut down the computers. Here are some hints for you.
Please verify your firewall settings. Turning off the WINDOWS FIREWALL on one machine would check if it were a fire wall issue. If so, you need to enable Remote Service Management in the following way: Control Panel > Windows Firewall > Allow a program or feature through Windows Firewall > Check 'Domain' field for 'Remote Service Management'. Done.
Additionally, Shutdown tool works using Samba over TCP, which means that remote computer must accept packets on TCP port 445.
So the only thing you need to do is to open Windows Firewall with Advanced Security and enable the rule: File and
Printer Sharing (SMB-In) and shutting down remote computer will start working.
Please try using "shutdown -i". It's less likely to make a mistake.
In Windows 7 and Windows Vista, the UAC strips administrative priveledges from users that are connecting remotely. This is called the Remote UAC LocalAccountTokenFilterPolicy. Instructions can be found at: http://support.microsoft.com/kb/942817/en-us. This applies to both Windows Vista and Windows 7.
Best Regards,
Grace
