Windows Vista also allows you to check the connectivity of your network connection using the Network Diagnostics Framework: An infrastructure and a set of built-in and extensible components that attempts to automatically diagnose and correct network connectivity problems. The usual way to run this check is to open Network Center and click the Diagnose Internet Connection link on the left Vista will either identify the problem and try to fix it, or will suggest that you send an anonymous report to Microsoft to help them improve the product.

Although, it can very difficult for windows to diagnose a network problem when it comes to specific broad scenarios:
A good example of a connectivity issue that provides incomplete information and can be difficult to troubleshoot is the following Internet Explorer error message page when a Web page cannot be loaded:
- The page cannot be displayed
- The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings.
For example, if Internet Explorer in Windows Vista cannot display a Web page, the error message text informs the user to click Tools, and then Diagnose Connection Problems. This invokesthe network diagnostic utilityto attempt to identify and correct the problem within the context of Internet Explorer. By diagnosing problems within their context, the diagnostics process is aware of the task and relevant information related to it, such as a URL, an email server name, or a wireless network name.
