Diagnose Connection Problems
If you have used Internet Explorer for any length of time, it is safe to say you have viewed this message. There are a few problems that might cause the Page Cannot Be Displayed message.
The first step to take is to make certain your Internet connection is active. To do so, open a new Internet Explorer browser window by double clicking the IE icon on your desktop, or from the Programs list. In the IE address bar, type the address of a website you don't typically visit. Can't think of any? Try www.randomwebsite.com. If the Page Cannot Be Displayed message is no longer displayed, the issue is with the particular website you were previously attempting to view.
If you still see Page Cannot Be Displayed when trying to view a new site, look for a Diagnose Connection Problems link in the Internet Explorer window. If you do not see it in the browser window, go to the Tools menu and click Diagnose Connection Problems. This will start the Network Diagnostics tool.
If the Network Diagnostics tool finds a problem, follow the steps provided by the tool. If the tool does not find an issue, or if Internet service provider seems to be inaccessible, try power cycling the modem. This might sound like a highly technical step, but it is really quite simple. To power cycle the modem, shut down the computer (do not restart). Unplug both the power supply cord and the connectivity cord (such as a phone line or Ethernet cable) from the back of the modem. Wait a minute or two, and then reconnect the modem's connections. Turn the computer back on, and see if the Page Cannot Be Displayed message is gone. If not, call your service provider, as there may be a service outage.
