Does anyone know where is is a complete howto on howto PXE boot Dban or a similar software we could use to wipe systems over the network with a PXE boot.
cant You can't PXE boot DBAN or perform network wipes.. Sorry You can network wipe computers open source style with FOG - http://www.fogproject.org/wiki/index.php?title=FOGUserGuide If you're comfortable jumping into PBE booting devices then FOG shouldn't be an issue for you.
