Right click on the IE\Chrome and select properties.
You will see user name or group name.
Click on Edit button and select the user or group name from which you logged in.
Verify that Permission for user name (Selected by u) is Allow or Deny.
If all the check boxes are checked under Deny option then IE\Chrome will not work for the selected user.
Make all the options checked under the Allow option and then open IE\Chrome.
It will work.
Reply me if it works or not if not then I will suggest u the other way.
