A really awesome utility for system admins or people who manage multiple computers is the PsExec tool from Sysinternals.
PsExec is a light-weight telnet-replacement that lets you execute processes on other systems, complete with full interactivity for console applications, without having to manually install client software. PsExec’s most powerful uses include launching interactive command-prompts on remote systems and remote-enabling tools like IpConfig that otherwise do not have the ability to show information about remote systems.
In a nutshell, this utility allows you to run any program as any user on any computer in your network. Needless to say this can come in handy when trying to gather diagnostic information or when rolling out new programs or updates to multiple computers.
Additionally, you can use PsExec as a “Run As” replacement if you run as a limited user account (i.e. non-administrator) when using your computer like I do. Since a standard user can launch the PsExec tool and not use “Run As”, you can do anything you need while running as a standard user.
