XP Network doesn't allow new computer to access

I have 3 desktops - one is brand new (configured today) - and all run XP
Prof. I have a wireless router - one computer uses wireless, other two
(including the new one) use ethernet. I'm working from the new machine so
ethnet card/cable clearly work.

I set up the new machine with option connect through hub or other computer.
>From this machine, no other machines are visible in My Network Places. I see
"Mshome" but when I select it I get this message:

"Mshome is not accessible. You do not have permission to use this network
resource. ...
The list of servers for this workgroup is not currently available."

>From other machines, I can see this machine but when I click on it I get:
"\\New_computer ...
The network path was not found."

Some of the things I've tried include powering everything down, including
the router, and then powering up. I've mucked around with the firewall -
turned it off and on and it made no difference.

I just killed 2 hours on the line with Dell and on their web site and they
wanted to sell me a $300 helpdesk service. Absurd...

I'm sure this is something simple but I haven't a clue as to how to solve it.

Thanks in advance.
