Hi; Hopefully you can shed some light on the situation I am encountering. I have a class set of 30 Dell Optiplex 745 workstations - and the drivers on the Web Configurator (primarily the tg3 driver) did not work with the Broadcom NetXtreme Gigabit network adapter in these workstations. So I built a new set of disks using a Feisty Fawn live cd and its Kernel to get the appropriate driver support. I am now able to get udpcast working to send a sysprepped windows xp pro image, ntfs - 80gb sata drive(ata-piix). I am now having the issue where machines are randomly failing with the newly casted image. I've been using lzop compression and have received a few errors on the sender - but the my main concern is that random machines get a disk read error (obviously wont boot) and some get NTLDR Missing error messages. This is very odd as it isn't always the same machines that get this error after a cast. I can restore a ghost image to those machines individually - they then initialize just fine. I've also tried to create disks using the Fedora Core 7 live cd with the same results. I am attaching a the very rough documentation I made as a reminder to myself on how I create the udpcast disks. Udpcast is great and works flawlessly on my older Dell labs here in the college! The issue has stumped me for about a month as I've tried different techniques on and off. Your insight is greatly appreciated!!
