Dear Customer,
Thanks for your post.
This kind of issue can have many possible causes. Therefore, we will have to perform a lot of troubleshooting steps. I''ve lists the steps below, please perform all of them and let me know the results.
1. Are all web sites not accessed via IE? Try to browse www.microsoft.com, what is the result?
2. Ping www.microsoft.com, note down the IP address returned, and then try to access www.microsoft.com via the IP address, what''s the result? If the page cannot be displayed, please capture a screenshot of the whole page because the page may give the reason why the access failed. You can send the screenshot to me at v-rxwang@microsoft.com.
3. Uninstall any firewall, internet security, or proxy software that has been installed.
4. Try to access the Microsoft website by name and by IP using Windows Explorer rather than Internet Explorer. What’s the result?
5. Does the workstation connect to the internet via LAN or a dial-up modem? Please provide the topology of the network so that we can determine how the network is structured. Is there any workstation else in the network experiences the same problem?
6. Verify your Internet Explorer connection settings:
a. Start Internet Explorer.
b. Click Tools, and then click Internet Options.
c. Click the Connections tab, and then click LAN Settings (for LAN, DSL, and Cable modem users); or from the Connections tab, highlight the appropriate dialup connection and click the Settings button (for dialup modem users).

d. Try to access the Microsoft website again.
7. Boot the computer into Safe Mode with Networking and then test the problem.
