Continual "Error 403 - Forbidden"

[mlints]

My kids crashed the PC yesterday, and after it re-booted, the only response I get from Internet Explorer no matter what web site I try to visit is "HTTP Error 403 - Forbidden". Luckily, Netscape Navigator is still accessing sites normally, but can anyone help me figure out what the problem is with Internet Exporer?
