PAExec lets you launch Windows programs on remote Windows computers without needing to install software on the remote computer first. For example, you could launch CMD.EXE remotely and have the equivalent of a terminal session to the remote server. PAExec is useful for doing remote installs, checking remote configuration, etc.

Microsoft's PsExec tool (originally by SysInternal's Mark Russinovich) is a favorite of system administrators everywhere. It just has two tiny flaws:

PsExec can not be redistributed

Sensitive command-line options like username and passwords are sent as clear text

We needed something that would overcome those two issues, and not finding a suitable replacement, decided to write out own.

Anyone can download and use PAExec. You can include it in your open source, freeware and even commercial applications. You may distribute it on your website, on CDs, mail to friends, etc. There is no cryptography built in so there aren't any export restrictions that we know of.
