I was trying out your server, PXE booting is something new for me. My goal is to PXE boot Linux Mint straight from a Windows host.
I have found your tutorial adjusted from Ubuntu at http://labalec.fr/erwan/?p=506 but the boot up is still hanging during the process and does not move forward.
No error messages (also had a few) after downloading the initial PXE script (says downloaded OK) and then hangs.
I suppose it is necessary to run winnfsd?
A step-by-step since the download of the software from sourceforge would really help. Have no idea what else is missing to complete the boot up procedure.
