-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Adam,
Can you share what was wrong in your dhcpd.conf file to help others debug similar issues? Even if it is a simple mistake, it can be useful. The options of the dhcpd.conf file can be a little confusing; so, it's always useful to have a reminder of how it works. We all make little mistakes that get overlooked while we dig in to other possibilities. :) Josh On Wednesday, April 18, 2012 12:42:55 PM Hechler, Adam wrote: > Hey everyone, > > Well, it turned out to be an issue with the dhcp.conf file.
