Hey Andy, I have WDS set up (having had it installed when SP2 was installed on my server) on a File and Print server. You do not have to enable any options in DHCP for PXE like you did in RIS for WDS. Just ensure that in the WDS MMC snappin, you have authorised the WDS box with the DHCP server, remove the PXE options etc from your DHCP server scope, and you should find that it all works ok. Hope this helps.
