My dad has a Windows Vista computer and suddenly today the internet didn't work. So we restarted it a few times and it still didn't work. We tried to ping google and it worked and in task manager it said that the wireless internet and hard line were both working. BUT in the processes iexplore.exe wasn't even there. And when we tried to run the shortcut for internet explorer it opened up a new page but then suddenly closed down. And when I tried to run iexplore.exe with command prompt it said it didn't exist. And THEN we looked it up in the program files and it was there but when we clicked on it nothing happened. I'm really confused and my dad has all of his work on the computer and cant send e-mails because the internet is not working and will not even start up a new page (doesnt even say cannot display page it just exits the page) so this is urgent. Please post any help.
