A Tale of Four Computers, A, B, C and a lonely D

[W. eWatson]

I have three desk top computers.
A: W2K Pro in an external building
B: XP Pro in the same building
C: XP Pro in the den

D is another PC, XP and a laptop

A, B and C are networked via MS networking
B can talk to C, but A no longer talks with either B or C
If I put D into action in the den, it can connect with C and B
If I put D into action in place of A, it will not connect to anything

I ran into this problem once before, but finally got the laptop, D, to
operate in the building. I want A back in the game, but would like to know
why the laptop D won't connect in the building.

What am I missing? Up until a two week vacation I took recently, A happily
connected to B in the building or C in the den. The A connection is not
behaving. It's a 15' ethernet cable attached to a 5 port Netgear switch box
(hub) in the building. BTW, my wife took her Linux laptop out to the
building, and plugged it into that cable, and it connected instantly.

This is pretty much solved. The A computer's ethernet card was dead. The D
computer, laptop, seems to have lost the LAN software setup connection
somehow. I'll worry about the laptop later.

Hi
As a future reference. Make sure that the Software Firewall on each computer
allows free local traffic. If you use 3rd party Firewall On, Vista/XP Native
Firewall should be Off, and the active Firewall has to adjusted to your
Network IP numbers on what is some time called the Trusted Zone (consult
your 3rd Party Firewall instructions.
