PsExec is a tool used a lot to execute a command on a remote computer.
PsExec, a tool from Microsoft can be found here.
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.
PsExec is part of PsTools.
See the July 2004 issue of Windows IT Pro Magazine for Mark's article that covers advanced usage of PsExec.
