This 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 a payload to install metsvc, disable the firewall, and add a new user metasploit on any Windows partition seen, and add a uid 0 user with username and password metasploit to any linux partition seen. The windows user will have the password p@SSw0rd!123456 (in case of complexity requirements) and will be added to the administrators group. Note: the displayed IP address of a target is the address this DHCP server handed out, not the "normal" IP address the host uses.
