Dean, I read your "bloody trail" account and it reminded me of a problem 
I had with a Dlink (I think it was a 514 or 524...I gave it to my 
brother so can't verify the number).  Turned out it wasn't vista 
compatible, but you probably already checked that.  I ended up 
"upgrading" the HP machine to XP from vista and it worked fine.   Back 
to your problem.  If it isn't a hardware problem, what I was trying to 
say in a few words and in re-reading my attempt, I think it was too few 
words (and maybe not the right ones)  grin.   I was suggesting turning 
off the firewall on the other machines, if you have them installed, 
until you get it working.   The turning off of IPv6 is done in Network 
and Sharing.  Go to manage connections and right click on the one you're 
interested in and choose properties.  You should find that IPv6 is 
checked by default in Vista.   I have had to turn it off (uncheck it) to 
get local networking to work on my setup.  Don't know why.  I'm not a 
network guru either.  Another thing I check in Network and Sharing is 
that network discovery is enabled and file sharing is enabled.  I 
remembered that you didn't know which network adapter had which MAC 
address.   I have two, also.  The way I find which one has which is by 
using the ipconfig /all    command that someone suggested.   It gives 
the address for the adapter, gateway, dns, etc along with the MAC.   
HTH, I know how frustrating the network probs can be, especially if they 
were working before.    George
