I do restart cups after every change in cupsd.conf.

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

The current contents of cups.conf is

MaxLogSize 20000

cupsctl

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

status_code=0 (successful-ok)

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