Thanks @Tom-Elliott . That actually makes a lot more sense now. 😁

I saw the greyed-out “Mass edit” button, but hadn’t worked out that I had to select multiple items (turn them blue) from the filtered list of hosts in order to be able to use that button to set values across multiple entries. Once I did, it worked as intended.

Thank you!

As you thought, it was a double DHCP server… Even though .6 was in bridge mode, the DHCP server on it was still enabled, unlike the other MikroTik switches we have. Disabling it brought the iPXE booting back. I’ve run a re-inventory task and am now running an image capture task.

I’ll have to keep a future eye open for that as we expand our classroom network.

Cheers!
