Utilities like Telnet and remote control programs like Symantecs PC Anywhere let you execute programs on remote systems, but they can be a pain to set up and require that you install client software on the remote systems that you wish to access. 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. PsExecs 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.
Installation
Just copy PsExec onto your executable path. Typing "psexec" displays its usage syntax.
PsExec works on NT 4.0, Win2K, Windows XP and Server 2003.
