I understand this may be able to be done with Samba? Anyone know the syntax for a CentOS 5.1 Samba client and what needs to be done to Windows 2008 Server to allow this (I suspect out of the box it wouldn't allow it)? I was hoping to use SSH with keys and script the login and execution of the native win shutdown command, but I have had troubles making any of the usual win SSH Daemons work under Windows 2008 Server x64. Any ideas would be appreciated! jlc
