OK.. I'm stumped.

My IE 7 appears to be working fine.  I can access all websites I have every
wanted with one exception.  What is this exception?

I recently installed MS Reporting Services on this computer.  All went well.
When I try to access the http:// site where all of my reports have been
deployed, IE 7 shows a blank page with the message:

"Bad Gateway 502".  [code=DNS_HOST_NOT_FOUND] The host name was not found
during the DNS lookup. Contact your system administrator if the problem is
not found by retrying the URL.

I have tried using another Browser (Firefox) and it accesses the page just
fine.  I have even went one step further by trying to access the http site
from another computer (also using IE7) via an Intranet.  It works fine.  I
have never seen any othe webpage that I have tried to access have a problem.
Only this one.

Where can I make changes.  It is not asking me for a password.  It is not
even partially bringing up the webpage.

I have tried clearing all history.  I have tried to check the settings in
the IIS section.  I have updated my IE7.  I have even uninstalled IE7 and
tried to use IE6 but to no avail.  I am using XP Professional.

Any suggestions would be welcomed.
