Problems getting cups 1.3.7-8 to share printers

[Margaret Doll]

I have a new RedHat print server running 2.6.18-128.1.6.el5.   I am  
testing printing across to a RedHat system running 2.4.21-58.ELsmp   
and a Mac system running 10.5.6

I originally started with the system-config-printer to install the
print queues.  For each print queue  Under Settings I checked

	enabled
	accept
	shared

Under Access Control

	I have set Allow everyone except    - there are no exceptions
listed.

When this did not allow printing across the network to the server,
I started editing /etc/cups/cups.conf.    I do restart cups after each
change in cupsd.conf

The current contents of cups.conf is

With these settings, the client RedHat system is still getting the
message that
	
	Network host 'name' is busy, down, or unreachable; will retry in 30
seconds.

The client Mac gets the message:

	Printer Paused.   Yesterday it was getting that access was forbidden.

The cups error_log on the Mac contains

cupsdReadClient: 14 POST / HTTP/1.1

On the server, I get the following errors at boot time:
