Putting that domain in your local DNS or hosts file pointing to an identical page on a local Web server (or even localhost!) would be interesting...

RS From: Carl Houseman [mailto:[email protected]] Sent: Tuesday, September 29, 2009 10:12 AM To: NT System Admin Issues Subject: RE: Vista, 7, etc method of determining if a network connection has "Internet Access" Did you actually lose Internet access or did it just tell you it had no access? I see Vista frequently become confused about Internet access - it says I don't have it, but I actually do. It determines Internet access by checking whether it can get to a certain MS URL - if not, then it reports Local Only. So I'm guessing maybe sometimes that site isn't responding, or it doesn't re-check very often, or some such thing. Carl From: Mike Gill [mailto:[email protected]] Sent: Tuesday, September 29, 2009 12:33 PM To: NT System Admin Issues Subject: RE: Vista, 7, etc method of determining if a network connection has "Internet Access" I had a problem recently with Vista claiming "local access only", which sounds similar maybe to what you're dealing with. Vista wouldn't allow me to get online. Ultimately I updated the wireless driver which solved it. But before that I tried per this advice found on google which may be helpful to you: - disabling any IPV6 protocols bound to the NIC - netsh interface tcp set global autotuninglevel=disabled - Edit registry to add DhcpConnDisableBcastFlagToggle (1) to MKLM\System\currentcontrolset\ services\tcpip\parameters\interfaces\{GUID for wireless card} - Or use this tool instead of the regedit: http://www.reviewingit.com/index.php/content/view/61/1/ The odd thing was I had varying degrees of success with each of the items in the list. But upon reboots I would lose access again. -- Mike Gill > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of > Richard Stovall > Sent: Monday, September 28, 2009 4:18 PM > To: NT System Admin Issues > Subject: Vista, 7, etc method of determining if a network connection has > "Internet Access" > > Does anyone have a good reference that explains exactly how Vista and > newer Microsoft Operating Systems determine whether a particular NIC has > "Internet Access?"
