Answer 1

Hi,

Do you remember any changes made on the computer prior to the issue?

I would suggest you try the following methods:

Method 1:

Run the network troubleshooter and check the results:

Using the Network troubleshooter in Windows 7 http://windows.microsoft.com/en-US/windows7/Using-the-Network-troubleshooter-in-Windows-7

Method 2:

Check the behavior by booting the computer in clean boot state. You may refer the below link on how to configure Windows to start in a "clean boot" state http://support.microsoft.com/kb/929135

If the issue does not persist you may continue with step 2 from the above link.

NOTE:Make sure you reset the computer to normal mode after the troubleshooting completes. Refer the section “Step 7: Reset the computer to start as usual”
