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.

See exploit/windows/misc/pxesploit for a version to deliver a specific payload.

Note: the displayed IP address of a target is the address this DHCP server
handed out, not the "normal" IP address the host uses.
