RunAs Extended is a command line tool modeled after the runas.exe tool that comes with Microsoft Windows. The important difference in this tool, is it allows you to pass the username and password during execution in order to automate the login process.

Since Microsoft does not include that ability, it makes it impossible to launch applications automatically as other domain users, or on another domain the machine has access to. This will allow that.

This tool was written for a company I worked for that worked on various domains and needed to launch the same tools for different domains based on need.
