difference unfortunately. I've also tried using the web server on the 
same machine as the PXE server and using 
'http://127.0.0.1/Software/Util1.iso' as the URL, again to no avail.

Presumably it uses network settings (such as the gateway) provided by 
the DHCP server?

Instead of "gpxelinux.0", have you tried "lpxelinux.0" (included in 
the same pxelinux package), with 2 or with 3 slash characters?
