Jim,
Thanks for your reply.  Yes, the other systems are defined in the /etc/hosts 
file.  I expect this is some sort of permission thing, but I'm not sure where 
to set it.  I configured it without a firewall (this is an internal system on 
my lan) but I'm not sure how to verify that no firewall software is running.  
I know I had this problem about a year and a half ago on my notebook - had to 
edit some file to allow others to connect - but I don't remember what file 
that was.
