Machine not found on network

[Guest]

I am having a seemingly bizarre issue with my home network. I have just 3
machines on the network, a laptop and 2 desktops, all running WinXP Pro, the
laptop with SP2, the others with SP1. Though the issue is not with the
laptop, but with one of my desktops. All 3 machines have been recently
reformatted with new OS installations. One of the desktops is connected
directly to my dial-up internet, and it is shared on the network. All 3
machines pick up this connection and can use it with no issues, and they can
connect and disconnect it. But, the machine that has the internet connection
connected to it, is not visible on the network. Neither of the other 2
machines can see it, but those 2 machines can see each other. The problem
desktop cannot see the other 2 machines. I have the same version of NIC
drivers on both desktops, as they both have the same model Netgear GA311
gigabit card. This is just a recent issue, as they were previously able to
see each other fine, it just came up the other day where it decided that I
could not see it. I had not changed any settings either. All were set to
obtain an IP addresses automatically originally. Right now, the internet is
still visible, but nothing else sharable, with the internet host desktop's IP
set to 192.168.0.1, and the other 2 machines on dynamic IP. I am probably
missing something completely or it is a simple answer, but I am fairly new to
home networking, though definately not new to computers, so feel free to give
me the technical details.

This problem would be typically caused by a misconfigured or overlooked personal
firewall, or other security component. There are several other possibilities
too.

You could look at "browstat status", "ipconfig /all", "net config server", and
"net config workstation", from each computer, and diagnose the problem. Read
this article, and linked articles, and follow instructions precisely (download
browstat!):
