requires in-browser authentication, such as university networks and hotel access points, Windows somehow dns.msftncsi.com malware magically knows. Windows also knows when your internet connection isn't working, and can differentiate between having local LAN access, no www.msftncsi.com/ncsi.txt windows 7 network access at all, or full internet access. But how? This week's question of the week is one I myself asked about this very topic. I guessed that there must be some online Microsoft

site that Windows is checking to determine the state of the connection, but I wanted proof, not just speculation. How does Windows know whether it has internet access or if a Wi-Fi connection requires in-browser authentication? Tobias Plutat and Jeff Atwood both replied with information about the Network Connectivity Status Indicator (NCSI) service, first introduced in Windows Vista. When called on by Network Awareness, NCSI can add information
Name Resolution For The Name Timed Out After None Of The Configured Dns Servers Responded Windows 7
about the following capabilities for a given network: Connectivity to an intranet Connectivity to the Internet (possibly including the ability to send a DNS query and obtain the correct resolution of a DNS name) NCSI is designed to be responsive to network conditions, so it examines the connectivity of a network in a variety of ways. 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. How does it work? Windows does indeed check a Microsoft site for connectivity, using the Network Connectivity Status Indicator site. There are a few variations of the connection checking process: NCSI performs a DNS lookup on www.msftncsi.com, then requests http://www.msftncsi.com/ncsi.txt. This file is a plain-text file and contains only the text Microsoft NCSI. NCSI sends a DNS lookup request for dns.msftncsi.com. This DNS address should resolve to 131.107.255.255. If the address does not match, then it is assumed that the internet connection is not functioning correctly. The exact sequence of when which test is run is not documented; however, a little bit of digging around with a packet sniffing tool like Wireshark reveals some info. It appears that on any conn
of the most common sites you'll run across is www.mstfncsi.com. This is because the url www.msftncsi.com is microsoft ncsi user agent generally used by Windows machines to verity that there is network

connectivity. A Windows machine (Windows 8, Windows 7 and even Windows Vista I believe) will try msftncsi hijacked to get a file from a web server to determine if there is network connectivity. There are two tests that a Microsoft Windows Client will perform http://blog.superuser.com/2011/05/16/windows-7-network-awareness/ to determine if there is outside connectivity to the Internet. The first one of such tests is being able to resolve msftncsi.com successfully and then retrieve a text time. The second test is more basic and it tries to retry said file directly via an IP address instead of using your DNS https://kx.cloudingenium.com/microsoft/servers/windows-servers/what-is-www-msftncsi-com/ server to resolve those addresses. This way Windows can determine if you are having issues with your DNS, router, etc. If it determines successfully that there is network connectivity you'll see on your network card status indications if there is IPv4 Connectivity and IPv6 Connectivity: In my case, I have only IPv4 Connectivity as my Internet Service Provider (ISP) does not support IPv6 yet. Below are a few details of the URLs that are used. As you might imagine there is an ipv6 and an ipv4 address: http://www.msftncsi.com/ncsi.txt is used to verify IPV4 connectivity and DNS resolution http://ipv6.msftncsi.com/ncsi.txt is used to verify IPV6 connectivity and DNS resolution Besides that there are some IP addresses it uses to try to verify connectivity without using DNS resolution. Below are a few: http://96.17.161.88/ncsi.txt http://216.156.199.152/ncsi.txt http://165.254.44.83/ncsi.txt http://96.17.161.90/ncsi.txt http://69.31.11.50/ncsi.txt http://165.254.51.43/ncsi.txt http://189.193.189.73/ncsi.txt http://189.193.189.83/ncsi.txt http://207.86.215.137/ncsi.txt http://207.86.215.178/ncsi.txt http://209.8.115.55/ncsi.txt http://209.8.115.86/ncsi.txt http://23.3.96.121/ncsi.txt http://72.246.55.16/ncsi.txt http://96.16.98.33/ncsi.txt Related PostsNginx: How to correctly use Time and Size postfix / parametersHow to: Have WordPress communic

The client was unable to validate the following as active DNS server(s) that can service this client.

And I went back through older logs of when the same thing would happen, and those two were the ones that popped up the most. However, this also popped up from time to time: Name resolution for the name www.microsoft.com timed out after none of the configured DNS servers responded.Click to expand... Name resolution for the name www.australian-charts.com timed out after none of the configured DNS servers responded.Click to expand... Now, I know my way around a computer, but this internet talk is pure "gibberish" to me, for lack of a better word. Additional information: The connection to my router is wired, not wireless. My PS3 and my laptop can stay connected/have never dropped a connection, while my desktop does it enough that it's beginning to bother me. Any idea as to how I can fix this? #1 clicheispasse, Jun 18, 2011 Mike Windows F

English: This information is only available to subscribers. An example of English, please! Comments: EventID.Net On Windows 10, this may be recorded due to a change on the DNS resolver design implemented with Windows 10. The operating system will try to resolve a name using all the network interfaces, even if some are not connected to the Internet. For this reason, timeouts may be experienced, websites may fail to open and so on. We disabled all but the active interface on one computer and the problem disappeared. x 11 Anonymous On a Windows 2008 R2 server - Setting STG enabled = FALSE on the switch ports solve my issue. x 5 Anonymous On Windows Server 2008 R2 I had to enabled "Spanning Tree Portfast" on my servers switch ports. x 102 Anonymous I fixed this problem by unselecting the TCPI\IPv6 protocol as it is not used on my network/ISP yet. x 96 Anonymous See T766017 and EV100150 for information related to www.msftncsi.com. x 60 EventID.Net From a Microsoft support forum: "This issue may be more hardware related, however, you may also try the following: 1. If the computers are connecting to a router, please ensure the router’s firmware is up-to-date. 2. Please run the following command in an elevated command prompt in Windows 7: netsh interface tcp set global rss=disabled netsh interface tcp set global autotuninglevel=disabled netsh int ip set global taskoffload=disabled 3. Disable SNP in Windows 7 by setting Registry (please perform a full-system backup first. ) as following: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters] EnableTCPChimney=dword:00000000 EnableTCPA=dword:00000000 EnableRSS=dword:00000000 If the keys do not exist, please create them and assign the value.
