How can I setup Home Sharing with a Sonicwall TZ 100?

Question

I have configured Home Sharing on 2 laptops and 1 desktop in my home network.  The two laptops (WiFi) see each other's respective libraries.  Neither can see the home desktop's library.  They are all on the same subnet.  I have created firewall rules on all devices to allow tcp 3689 and udp 5353 traffic.  I even went as far as disabling the firewalls on the computers (all three) completely.  I have enabled Multicasting on the Wifi interface of the Sonicwall.  The Sonicwall is setup in basic wan/lan mode with ALL LAN interfaces in the same port group to ensure they co-exist on the same subnet.  I am running Itunes 10.6.
I still can't see the desktop computer's library and it can't see the two laptops.
What am I missing?
Thanks in advance,

First, make sure you've got the home share set up on both computers, as per the following document:
iTunes: Setting up Home Sharing on your computer
Have both computers running and have iTunes open on both computers.
Now, in the iTunes on the computer you want to transfer music to, select the library that you want to transfer music from, as per the following screenshot:
Once the other library loads, go down to the bottom of the screen and in "Show:" select "Items not in my library":
If you want to import all of the songs you can now see, head up to the iTunes menu bar and go "Edit > Select all". Then head down to the bottom of the screen again and click the "Import" button in the bottom-right-hand corner.
