Joe,

Try changing the server settings and leave the onboard nic. Your problem is most likely caused by the implementation of PXE booting in Intel Landesk 0.99 and will persist even if you swap out the nic. My Intel motherboard had an onboard Intel eepro100 nic and it couldn't boot without making those changes. I think you'll find you have to change these settings no matter what nic you use.

Good luck and let us know how you make out.
