I think getting Samba setup is potentially difficult - you don't describe it in enough depth to say what exactly the problem is (my guess - you need to access the machine by using its DNS name or IP address, the "browsing the network neighborhood" doesn't even work all the time on a properly configured Windows network.)

However, if its a relatively small amount of traffic between Linux machines, I would be more inclined to use ssh / scp / sftp.  It takes a little effort to setup (generate RSA keys, copy the public key to the other machine*, etc.)  It is very convenient once its setup.  You can also use something like filezilla, winscp, or best of all sshfs.

* something like the following works:
    cat .ssh/id_rsa.pub | ssh user@othermachine "cat - >> .ssh/authorized_keys"

Does anyone have any suggestions how to proceed??
   
I'm no expert, but this might help move things on.

I assume each machine can ping the router, as their Internet connextions
work.  However, can each machine ping both other machines?

Hi Steve,

Thanks for the suggestion - I'd even forgotten that ping existed!  I'll have to build me a Little Reminder Script "when this, then that"!!

Strangely, I don't seem to be able to ping the gateway... but after several false starts, I get the following when pinging the desktop from the laptop & the LT from itself:
