First off, thank you very much for your help.  Some time after I sent
my original message to the list, my brother suggested that I try this:
http://192.168.1.100/gallery2/main.php (192.168.1.100 being the IP
address of our system that has the server running on it.)  This worked
perfectly.  Of course, I shouldn't have to replace the domain name with
the IP address just to run Gallery2 and Squirrelmail from our new
Fedora 10 system.  So, inspiration struck me, and the problem has been
fixed ever since.  The complete fix was adding this line to the
"Problem System":
192.168.1.100   afolkey2.net            www.afolkey2.net

So, I put a line in 192.168.1.101's /etc/hosts file telling it to map
requests for afolkey2.net and www.afolkey2.net to 192.168.1.100 (the
address of our server.)  Perfectly solved my problem :)

Again, thank you for your efforts on my behalf.
