Unidentified Network while using network bridge

    So I have a laptop w/ wireless (using XP Professional) and a desktop (using
    Vista Ultimate). My laptop connects to my router thru wireless, and it
    connects to my desktop thru a ethernet cable. I bridged my wireless and
    ethernet connection on my laptop in order to connect my desktop to internet
    wirelessly. This method works fine for several weeks, until one day it
    suddenly stops working. No matter how I disconnect and reconnect everything,
    reset my router, disable/re-enable network adaptor, the desktop still showing
    me that it has connected to a unidentified network (public) with local area
    connection (sometimes it showed limited connection as well). However,
    sometimes my desktop has 2 connections: one is unidentified and another one
    is the normal connection I would get if I successfully connected to the
    internet. During this situation, even though my desktop can't connect to the
    internet, I have access to my router.

    I have tried my best to describe the situation, I sincerely hope that
    someone could help me here.

    p.s.: my laptop could access internet thru wireless normally

    I should have explained in first post, I have same setup and had Trend
    firewall connected on both machines once I disabled Trend & used MS firewall
    only (both PCs) and all other setting correct everything connected no
    problems since (10 mths ago)
    Below are some sites that will assist to get connections correct:

    I did try to disable the 3rd party firewall and use MS firewall, but nothing
    changed.
    Thanks for all the links, but I don't think they could solve my problem.
    Since I didn't change any setting, and I my desktop was able to connect to
    internet wirelessly b4, so I don't think it's the problem of the setting.

    Also, I just discovered that the CAT-5e cable I'm using is a straight cable,
    which is not supposed to use to connect 2 computers together. However, most
    of the network adapters nowadays can do the crossover data automatically even
    if the cable is a straight one (that's what I read from wiki). So is it
    possible that this problem occurs because the network adapters' data
    crossover ability is broken?
    Even so, it still doesn't explain why my desktop is still able to connect to
    the router, but can't connect to the internet.
