In reply to Michael. At the time the article was written and for the version of BlueCat DHCP appliance the customer used, there was no Option 66. BlueCat support verified it and told us what to use. Webster

Carl,
Great story but you have got it a bit mixed up: the problem is that BlueCat DHCP *does* support option 66.

The Wireshark capture would have come from a working environment with Microsoft DHCP. When you configure option 66 on a Microsoft DHCP server, the Microsoft server never sends DHCP option 66. DHCP option 66 would have been missing in the packet capture. When you configure option 66, a Microsoft DHCP server will send the server IP address in the next-server field of the DHCP header instead, and this is what most clients expect.

The conclusion is the same: with BlueCat DHCP you need to use the Next Server option, instead of configuring DHCP option 66.

Michael.
