[syslinux] syslinux 6.03pre17 + gpxelinux.0 + iso from http not working

Have you tried with 3 slash characters instead of 2? I mean, 
replacing "http://" with "http:///".

 LABEL util1
    MENU LABEL ^Util1
    LINUX memdisk
    APPEND iso
    INITRD http:///ourserver.ourdomain.com/Software/Util1.iso
