Hi Michael, Firstly thanks for the prompt response - appreciated! Comments in-line...

We have been running this configuration for nigh on 10 years, as unfortunately as with many large enterprises (30,000+ servers) the DHCP/DNS team is in a different country (and chain of command) to the server/OS engineering teams. Fixing this may not be as easy as I'd hoped -- I am curious as to why we wouldn't have seen this before though? > The easiest fix (if you can do it) would be to stop the QIP server from > handing out its apparently spurious next-server address. I wasn't even aware that it did until I stumbled across this issue and setup a sniffer. Looking through the ISC dhcpd configuration guide, the next-server directive defaults to the IP address of the DHCP server itself if not specified. I guess we could experiment with hard-coding the next-server to 0.0.0.0 or something to see if gPXE ignores it? Any ideas here? Lastly - excuse my ignorance but what's the difference between gPXE/iPXE? Cheers, Tim -- Tim Wright e: tim at binbash.co.uk
