I need to shutdown and / or reboot remote system. Can this be done remotely without physically being next to the server?
You might also want to checkout Mark Russinovich's PsShutdown utility. It's similar to the native Windows shutdown command, but also allows you to logoff the console user or lock the console.
I had a similar post on Stackoverflow and included a reboot script that waits for the server to come back.
You can also use psshutdown from the SysInternals tools.

Usage: shutdown [/i | /l | /s | /r | /g | /a | /p | /h | /e] [/f] [/m \computer][/t xxx][/d [p|u:]xx:yy [/c "comment"]]
No args Display help. This is the same as typing /?. /? Display help. This is the same as not typing any options. /i Display the graphical user interface (GUI). This must be the first option. /l Log off. This cannot be used with /m or /d options. /s Shutdown the computer. /r Shutdown and restart the computer. /g Shutdown and restart the computer. After the system is rebooted, restart any registered applications. /a Abort a system shutdown. This can only be used during the time-out period. /p Turn off the local computer with no time-out or warning. Can be used with /d and /f options. /h Hibernate the local computer. Can be used with the /f option. /e Document the reason for an unexpected shutdown of a computer. /m \\computer Specify the target computer. /t xxx Set the time-out period before shutdown to xxx seconds. The valid range is 0-600, with a default of 30. Using /t xxx implies the /f option. /c "comment" Comment on the reason for the restart or shutdown. Maximum of 512 characters allowed. /f Force running applications to close without forewarning users. /f is automatically set when used in conjunction with /t xxx. /d [p|u:]xx:yy Provide the reason for the restart or shutdown. p indicates that the restart or shutdown is planned. u indicates that the reason is user defined. if neither p nor u is specified the restart or shutdown is unplanned. xx is the major reason number (positive integer less than 256). yy is the minor reason number (positive integer less than 65536).
