On Server 2008's Start menu I can select "Log Off", "Lock", "Restart", and "Shut Down"
I wish to remove the "Restart" and "Shut Down" options for all users so that they can't accidentally click on this and are forced to use the manual command options. How do I do this?
There is a local security policy or GPO setting that allows you to remove the commands and only allow "log off". We use it on some servers.

Edit your group policy settings to remove these options:
GPEDIT.MSC -> User Configuration -> Admin templates -> Start menu and taskbar.
Find:
Remove and prevent access to the Shut Down, Restart, Sleep, and Hibernate commands
And set to enable.
