Trying to add a Vista computer to an existing XP home network

[Guest]

I got a new PC with Vista and tried to hook it into my existing home network
which is all XP. Things weren't working for awhile so I went to an existing
network computer (an HP) and created a new wireless network with the same
name but different key and authentication/encryption type as the original
network.

The original issue I was having with the Vista computer got resolved and
now, it can access all of the computers on the network EXCEPT the HP whose
settings I changed. The error message I get from the Vista is that it's
pinging HP but not getting a response back. I'm guessing I need to change the
original HP back but I have no idea how to do that.

Also, even though I can access all the computers (excpet HP) from the Vista
one, the computers can see the Vista computer but get prompted for a UN/PW
when they try to access it. I didn't think I gave it a UN/PW. How do I find
out what that is? Or better yet, how do I disable it? I think this is a
separate issue from the one above but I'm not sure.

I know next to nothing about networking so if someone could give me some
pointers on how to fix these things in very plain, simple English, I'd really
appreciate it.

Do all of the computers have connectivity to the Internet? Is the only problem
the Vista computer trying to access the HP computer?

Is the Vista computer running Password Protected Sharing On or Off?

Look at logs from "browstat status" and "ipconfig /all", from the HP computer,
the Vista computer, and one other computer, and diagnose the problem. Read this
article, and linked articles, and follow instructions precisely (download
browstat!):
