Yes. We are configuring all our company's desktops by hand. I guess that's how the hostname is set.

Using option:host-name works as expected.

Yes it does. Thanks a lot for the help and the code.

Where are the workstation names set? If they are locally to the
workstations, (rather than being set by DHCP) then the machines will be
sending their hostnames in DHCP requests. If so you should be able to
use dhcp-match to look at the hostname options.

dhcp-match=set:baz, option:domain-name, foobar-

It's not an ideal solution, but it might work for you.


Simon.
