booting disallowed

Tue Dec 11 13:21:56 UTC 2007

Hi Simon

Need some moreinformation here...

What version of dhcpd? What platform? (redhat, suse, freebsd, solaris,
aix, etc..) Did you build dhcpd from source or are you using a prebuilt
package?

Can you post your dhcpd.conf and a short description of your network
topology?

regards,
-glenn
