I know I'm virtually writing to myself, but still able to get a few votes so hopefully some win32 monks are following along, otherwise I'll spawn a new thread. Starting to notice that my psexec approach to run a forced shutdown isn't always going through, because when I run a

wmic os get lastbootuptime

doesn't list the current date / time even after successfully triggering a psexec forced reboot over 6 min prior to checking. ie.:

psexec.exe \\host-u domain\japh -p obfuscate -i -d cmd /c shutdown /r 
+/f /t 0

but perhaps my psexec syntax is off or else I should be using another method to remotely force shutdown of windows servers.
