One computer in peer to peer no longer seeing other computers or being seen

I set up a friends peer-to-peer network a few years ago. everything has been
working well until recently (an he claims nothing has changed on any
machines, ha!).

All 4 computers are WinXP SP2. Every computer is seeing all the other
computers on the network shared folders & printers. Recently the laptop does
not see the other computers and the other computers "see" the laptop but
can't connect to it.

The laptop does still connect to the internet
The laptop can ping the other computers successfully
All computers are part of the same workgroup and on the same subnet
No viruses or spyware detected on any systems
AV and (Windows) firewall have been disabled for testing purposes
No other 3rd party firewalls are installed
File & Printer sharing is enabled on all computers

I do see the laptop listed in the other computers Network Neighborhoods, but
get the following message when trying to connect "\\Laptop is not
accessible. You might not have permission to use this network resource.
Contact the administrator of this server to find out if you have access
permission. The network path was not found"

No computers are listed in the network neighborhood of the laptop (including
the laptop). If I try to search for a computer nothing is found. If I try to
connect to a previously mapped network drive I get the above error message.

Any ideas?

Thanks
