This is a general error that means that IE is unable to connect to the
website on the IP address it was given.
This can be caused by a multitude of problems, but DNS is returing an IP
address.
If DNS was unable to resolve the name to an IP address you would receive
this error in your Browser:
Client error
Host name lookup for 'www.example.com' failed
So we know IE is getting an IP from DNS for the name, BTW what was the
website name?
I suppose the next step is to see what the MTU you can ping that site with
using the same command your used to ping your internet gateway.
ping www.example.com -f -l 1464
Some websites are not pingable so you'll have to use a pingable site. Here
is an example of pinging www.yahoo.com:
W:\>ping www.yahoo.com -f -l 1464

Does this server have RRAS and is it configured for incoming connections?
292822 - Name resolution and connectivity issues on a Routing and Remote
Access Server that also runs DNS or WINS:
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q292822
This can also cause DNS problems if you have the DNS proxy enabled in RRAS.
