1.) Are you able to resovle the website by a FQDN, internally (for users
with private ip will the website resolve with an internal ip) and
externally (for internet users will the website resolve with an external
ip)?
 
2.) Does the Website have the a host header with the same FQDN?

        Thanks for the reply. It isn't an IE problem. It happens from
where ever you try it. I am at my office and it does it. His programmer
experiences the same thing from his office. I terminal serviced into the
site and it does it from the server itself.  In the past, rebooting the
server corrected the problem. However, this morning the reboot did not
resolve the problem.
         
        The Event Log shows error 14141 but nothing in that applies.

                Hi Larry, have you configured IE properties to bypass
the proxy server, and under the Advanced... button, under Exceptions
entered the FQDN (example: *.companyweb.com)?

                        I have a client with SBS 2000 with ISA. They run
their web site on it. We have started getting the occassional problem
that the web site becomes inaccessible. When viewed from IE, the error
is:

                        The server has detected a proxy chain loop. This
condition might indicate a configuration problem in a proxy server. 
                        This would indicate that there is a problem with
the configuration between multiple ISA servers. However, this is the
only one. Anyone have any ideas of how to resolve this?

                        Thanks. 

                        Larry
