Benefits and Purposes of the Network Connectivity Status Indicator. Windows Vista includes a feature called Network Connectivity Status Indicator (NCSI), which is part of a broader feature called Network Awareness. Network Awareness collects network connectivity information and makes it available through an application programming interface (API) to services and applications on a computer running Windows Vista. With this information, services and applications can filter networks (based on attributes and signatures) and choose the networks best suited to their tasks. Network Awareness notifies services and applications of changes in the network environment, thus enabling applications to dynamically update network connections. Network Awareness collects network connectivity information such as the Domain Name System (DNS) suffix of the computer and the forest name and gateway address of networks that the computer connects to. When called on by Network Awareness, NCSI can add information 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. Web site that exists only to support the functionality of NCSI. Overview: Using NCSI in a Managed Environment. In a managed environment, you might choose to use NCSI because of the way it supports services and applications that require network connectivity. You can disable NCSI, however, by changing a registry setting. How NCSI Communicates with a Site on the Internet. The following list describes how NCSI might communicate with a Web site to determine whether a network has Internet connectivity: Specific information sent or received. Type of Request that NCSI Sends. What NCSI Expects to Receives if Connectivity Exists. A request for http: //www. Page called ncsi. Microsoft NCSI(Page headers disable caching.)A request for DNS name resolution of dns. Resolution of the DNS name to: 1. Default setting and ability to disable: By default, Network Awareness (which includes NCSI) is enabled. NCSI can be disabled by changing a registry setting. Triggers: Network Awareness and its subfeatures gather information flexibly—that is, by using complex algorithms that respond to changing network conditions. This means that triggers can vary, but the following are examples of typical triggers that can cause NCSI to communicate across the Internet. A user first logs on after the computer has been restarted. The computer connects to a different network. The computer is brought into a hot spot (public wireless access area) that requires sign- in. User notification: NCSI does not notify the user before attempting to collect information. It does notify the user or the application when there are changes in connectivity (for example, loss of Internet connectivity). Note that an application that uses NCSI can be written to include user notifications if appropriate to the design and function of the application. Logging: NCSI does not log events in Event Viewer. Encryption and storage: NCSI does not use encryption (both the requests it sends and the responses it receives are standardized, as shown in the table earlier in this subsection). IIS logs are stored on the server at www. These logs contain the time of each access and the IP address recorded for that access. These IP addresses are not used to identify users, and in many cases, they are the address of a network address translation (NAT) computer or proxy server, not a specific client behind that NAT computer or proxy server. Privacy: The privacy statement for Network Awareness (which includes NCSI) is on the Microsoft Web site at: http: //go. Link. Id=7. 06. 82. Transmission protocol and port: NCSI uses HTTP over port 8. Controlling Communication Between NCSI and a Site on the Internet. You can prevent NCSI from connecting to http: //www. The following subsections provide more information. How Preventing NCSI from Communicating Across the Internet Can Affect Users and Applications. If you set a registry key to prevent NCSI from connecting to http: //www. Internet connectivity might work more slowly. Also, if a computer running Windows Vista is brought into a hot spot that requires sign- in, the computer might not detect the hot spot. Procedures for Controlling Communication Between NCSI and a Site on the Internet. The following procedure describes how to change a registry setting that prevents NCSI from communicating across the Internet. To Prevent NCSI from Communicating Across the Internet by Changing a Registry Setting. For best results, close all programs on the computer on which you are changing the registry setting. Setting the value to 0 prevents NCSI from connecting to a site on the Internet during checks for connectivity. So i assume, that you’re on this page from another device that has internet. The error is too general, it doesn’t tells us why, where and how has it not got the internet, instead it just says “no internet”. So to fix this issue, we will have to troubleshoot it as there is no straight forward fix but by the end of this guide, you should be able to fix it. Method 1: Check Connectivity. Make sure that your router or whatever device is responsible for internet, is receiving internet from your ISP. If it is a wi- fi device, then connect your phone or another wifi enabled device to this router/modem and see if gets the internet. If it does, then the router is fine if it doesn’t then speak to your ISP because you’re not getting the internet. If you’re already connected to this router/modem from another device which is working fine, then you have the internet. Now test it via computer, do the following: a. Hold Windows Key and Press Rb. Type cmd and Click OKIn the black command prompt, type: ping - t 4. Hit Enter. It should show the following lines: Reply from 4. TTL=5. 3Reply from 4. TTL=5. 3Reply from 4. TTL=5. 3This means, the internet is connected, the last numbers could be different but this is what it should show, if it shows this then the internet is connected, if it shows “Request Timed Out” or anything else then the internet is not connected. Make sure, that your wireless or wired adapter is connected to your router, keep this window open, and keep checking it after performing each step below. When it starts to show replies, issue would be fixed. Method 2: If Router/Modem Has The Internet. If the router or modem has the internet, then most probably the issue is software related, on the computer getting the DNS. This works in most cases, where the issue is originated due to a system corruption. You can download Reimage Plus by Clicking Herea) Click Start button and search for cmd – note: we are now opening a new command prompt, do not close the previous one already pining. Right Click cmd and select Run As Administatorc) In the black command prompt that opens up, type the following four commands. Hit Enter after each command. The five lines shadowed below are 5 separate commands; make sure you type them exactly as i have typed, if a space or a letter is missed, the command will return error. C: \resetlog. txtnetsh winsock resetipconfig /flushdnsipconfig /releaseipconfig /renew. After this is done, check if it is now able to connect, see the command prompt we used to ping, is it getting the replies? If it is, issue is fixed If it isn’t, try STEP 3. Method 3: Power Cyclea) Power off your modem and your router. Wait 1. 0 minutes and power them back on. Make sure computer is connected (if it wi- fi) if it is wired (then it already is connected)d) Look at the command prompt to see if it is now getting replies. Wait 1- 2 minutes after powering it up before moving to STEP 4: Method 4: Reset Google Chrome. This step is not technically related to what we did in previous steps, but i would still recommend performing these instructions below. Hold Windows key and Press Rb. In the run dialog that opens up, type. If you are running Windows XP%USERPROFILE%\Local Settings\Application Data\Google\Chrome\User Data\If you are running Windows 7/Vista/8/8. LOCALAPPDATA%\Google\Chrome\User Data\Click OK. This will open Windows Explorer with a bunch of folders, right click the default folder and select rename, rename this folder to default. If it tells you that Chrome is already in use, then save these steps, reboot your computer and without opening Chrome perform these steps. After the default folder has been successfully renamed to default. Chrome. PRO TIP: If the issue is with your computer or a laptop/notebook you should try using the Reimage Plus Software which can scan the repositories and replace corrupt and missing files. This works in most cases, where the issue is originated due to a system corruption. You can download Reimage Plus by Clicking Here.
