Since I was having trouble setting up a Samba server for my internal
network here at home, the DIAGNOSIS.txt file said something about
expecting the /etc/hosts file was set up correctly for the network. 
Checking it only showed one entry...127.0.0.1    localhost.localdomain.

Since my network was setup on DHCP and my DSL router was the DHCP server
(I'm not running a DHCP server on my Linux box), there was no way to put
a static IP address in the hosts file on the Linux box.  So, I got
around that by disabling the DHCP server on the router and assigned
static IP's for each of the machines on the network.

That worked until I rebooted my Linux box and I got the same kind of
error Fred was getting when the boot process tried to start the lpd.  I
went to the /etc/hosts file and checked it again and saw my error.  I
had changed the 127.0.0.1    localhost.localdomain entry to 
192.168.0.100   LINUXHOST.  On the advice someone else gave on the list,
I added back an entry in the /etc/hosts file for the 127.0.0.1  
localhost.localdomain, started the lpd and it started just fine.  I no
longer get that error message on startup.
