I'm reinstalling XP on a very old laptop with a dead cd drive. I don't have any floppy drives and it doesn't support usb booting, so PXE is my only option.
Can I set up a PXE server on my Windows 7 Desktop? Thanks!!
Yes, you can, but you'll need to configure it as a DHCP server as well. The primary piece of software you'd use is TFTPD32. It's pretty well known for being reliable on a Windows system.
If you have another system with which you can play around, I've just configured a Debian Linux based TFTPD/PXE server that's running smoothly in my organization. Let me know if I can help further.
