Windows 7 states No Internet Access even when I can get out to any site??
I just recently installed a fresh version of windows 7 on my machine at work. I can get out to the internet and locally on our network but the icon in the taskbar states that I have no internet access for my domainwhen indeed I do.. We have a proxy here (Bluecoat)that requires a username and password to get out but seeing that I can get to the internet no problems I shouldnt have this message. I also noticed when I try to synch my blackberry it states that I dont have an internet connection. Any ideas? Thanks in advance!Denny

Hi Denny, I would like to share the following information with you. Network Connectivity Status Indicator (NCSI) is a feature since new Windows Vista. It is designed to be responsive to network conditions, so it examines the connectivity of a network in a variety of ways. One test failed, NCSI may report a error, even if the networking actually can be accessed fully. For example, NCSI tests connectivity by trying to connect to http://www.msftncsi.com, a simple Web site that exists only to support the functionality of NCSI. Please try to manually visit the following website, you should see Microsoft NCSI. http://www.msftncsi.com/ncsi.txt For more information about NCSI, you can refer to the following article: Appendix K: Network Connectivity Status Indicator and Resulting Internet Communication in Windows Vista http://technet.microsoft.com/en-us/library/cc766017.aspx Sometimes, we can access the http://www.msftncsi.com/ncsi.txt file in IE, but the NCSI still fails. It is because the NCSI traffic is not sent via IE but via WinHTTP component and use proxy specially. A proxy server which requires user authentication won't allow it access Internet. Basically, NCSI must perform extra steps in an environment that has proxy servers. Web Proxy Automatic Discovery (WPAD) proxy detection is recommended. If WPAD is not used, configure WinHTTP proxy settings to help NCSI: netsh winhttp set proxy command For more information: TechNet article Automatic Discovery for Firewall and Web Proxy Clients http://www.microsoft.com/technet/isa/2004/plan/automaticdiscovery.mspx 927551 Windows Vista Support WebCast: Troubleshooting Network Issues on Windows Vista - New Network Diagnostics http://support.microsoft.com/default.aspx?scid=kb;EN-US;927551 937151 You cannot connect to the Internet from a Windows Vista-based computer that uses a local .pac file http://support.microsoft.com/default.aspx?scid=kb;EN-US;937151 Hope it helps.
