We have a computer that many staff use to access the internet.  One user gets the message that there is no connection.  I logged on to the computer as 3 users and all had IE except one.  What would cause this?

could be GPO could be a deleted icon in their profile for IE?

Users account internet access can be blocked by policy from the DC or local policy in work group.

I'm the only Admin so that is probably not the cause.  I also found out it is not just one user but a few.  Could it have anything to do with AD?

Okay - the ugly answer is possible malware for that user.  If a user's account gets malware or drive-by infection - normally other accounts are not affected.  Unless of course the user does something additionally silly like installing software.

I suggest you check internet options > connections > lan settings and look at the proxy settings.  Make sure they are not redirected.

Other thing is get the IP address of a website you know.  Then put that in the URL i.e.
http://72.29.71.170.  If website comes up the account is being redirected.  This eliminates DNS from consideration.  Also make sure you can ping the default gateway of the external (public) router.  Traceroute that to see how you are getting to the internet.

Keep in mind a redirected proxy to a server that may not always be available in the cloud - hence timeouts to any location.  When redirected proxy to a server that comes back as reachable - everything works again.
