Subject: [dhcwg] Getting DHCPNAK

This is the log.  Most machines on the LAN do not have a problem.  A few
do this.  This started to happen after switching from using Cisco 678
DHCP to Redhat Linux 7.1.  I switched back to cisco so all may be
opperational.  But I wish to use Linux DHCP.  The dhcpd.conf file is
included below.  Any advice is appreciated.   I have already hunted the
internet for tips and those I tried did nothing.

Many Thanks,

Durwin
