PXE - Booting issue (strange)

That, or, configure the other dhcp server to point at the new fog server as well.

[ITCC]

nope, one DHCP server

it’s back in the office now and still doing it, so not switch equipment.

@ITCC Does this system have a dhcp reservation set on your dhcp server?

[ITCC]

have checked twice, no reservation.

Also works after pause, thought that would still resolve incorrect reservation info.

[ITCC]

we have a winner!

@ITCC And…

My next step is to confirm that everyone is in the same subnet then setup a packet capture into a pcap file so we can see where that alternate IP is coming from.

Tom Elliott, got me thinking about a “copy” of our windows DHCP server on another DC, that was a backup to when we had issues.
this DHCP is never to be switched on and it’s approx 3 years out of date.

Guess what, somehow (someone) has authorised this scope.

• Although, no stats showing used IP’s, when deactivated the PC continued beyond the loop.

Thanks to everyone who helped.

Check your DHCP option 66 and 67.

Is the dhcp discovery tool ready for prime time?

@Sebastian-Roth Have you had any time to mess with this?

[Tom Elliott]

@Wayne-Workman I’m fairly sure Joe already is on it. Though of course Sebastian probably needs the “finishing” touches lol.

Have been on a short holiday far away from net and power… but working on it right now.
