Unfortunately, because of the moronic use of ping to cause denial of
service attacks its use as a diagnostic these days is increasingly limited.
Try using telnet instead. To instrument your test use netstat -s
E.g. I just did that with the address that you gave with the following
five commands entered in a command window:
netstat -s >before.txt
telnet 207.46.244.188 80
<wait for the screen to clear and type GET /
then press Enter
>
netstat -s >after.txt
fc before.txt after.txt >diff.txt
notepad diff.txt
Here is a summary of that comparison (by subtracting the changed
statistics and reporting only non-zero results):
Packets Received = 36
Received Packets Delivered = 36
Active Opens = 1
Segments Received = 36
Segments Sent = 30
Note: for some reason my first attempt was dropped before I had
had a chance to type the GET command.
Make sure that you minimize the number of other Internet applications
to make your results comparable. Do more than one capture
if necessary to prove that your results are repeatable.
Note that this procedure bypasses the use of DNS.
Your ping test showed that your DNS seems to be working fine
but if the above test works try it again with the symbolic address.
In order to bypass the dnscache and ensure that you do a real lookup
you should first do:
ipconfig /flushdns
(After that I would also do:
ipconfig /displaydns | find /i "microsoft"
just to be sure that no unexpected entries are being added by your
HOSTS file.) Then if you do the same kind of comparison of before
and after statistics you will probably see some indication of the lookup
being done (e.g. with changes in Datagrams statistics).
If it turns out that these tests are successful we will have proved that
connectivity is not the problem. Therefore, it would have to be something
particular that IE and that site are both doing together.
Good luck
