fyi to all... A common networking issue i've often seen come up with XP (don't remember if same is true for Vista).. If you seem to have networking problems and you use a 3rd party firewall product (i.e. you don't use Windows firewall) make sure that Windows Firewall hasn't managed to turn itself back on! => If Windows firewall is turned on at the same time as your 3rd party firewall, Windows firewall will interfere with your network communications. You shouldn't have two firewalls running concurrent (and you might not intend to but Windows sometimes turns itself back on) => And i finally found (at least one way) Windows firewall turns back on: If you happen to run the Home Network Setup Wizard windows may turn the Windows Firewall back on! So if you need to run that Wizard be certain to check and turn Windows Firewall back off@!
