We have extended our default zone to Internet zone. Here are the URLs:

http://spserver:80 (default zone)
http://spserver:8080 (internet zone)

When I use above URLs, they work fine, however, we configured our firewall
and DNS servers so users can access to SharePoint contents through the
following urls:

http://spserver:80 (default zone) ==> http://intranet.OurCorp.com
http://spserver:8080 (internet zone) ==> http://extranet.OurCorp.com

The problem:

The problem is all users are being redirected to http://spserver:80  or
http://spserver:8080 at this point.

I understand this can be fixed by alternate access mapping.

Could you just type how the AAM listing should look like for the above
access mapping?

Thank you,
Max

Hi Max,

The AAM will help format all those internal url links(within MOSS response)
to the publich URL you specified in the AAM mapping collection(depend on
the zone the internal url/request url  ).

For your scenario, you have the following DNS mapping to internal site:

then, for http://spserver:80 site, since it is access internally, you just
need one AAM mapping as

INTERNAL                ZONE                PUBLIC
http://spserver:80    default                http://intranet.OurCorp.com

while for the http://spserver:8080 site, since it is accessed from both
internal and external, you will need to have two mapping record for it.

INTERNAL                                    ZONE                PUBLIC
http://spserver:8080                    internet              
http://extranet.OurCorp.com
http://extranet.OurCorp.com     internet              
http://extranet.OurCorp.com

Thank you for help.

I have applied the mapping the mapping you suggested to the AAM. The problem
is  *every* request are redirected to http://spserver:80.

That means all of the requests through the following URLs are redirected to
http://spserver:80
http://extranet.OurCorp.com
http://intranet.OurCorp.com
http://spserver:8080

I have carefully tested and checked and there is no typos, and DNS, Firewall
NAT are working perfect. It is just AAM is not working what so ever.

This has taken a week of my time to investigate and I couldn't find a clue.
Very frustrating.

Is there any internal tool that can monitor and troubleshoot why AAM is not
working? The sharepoint server includes the latest service pack. Am I
missing any particular patch?

Thank you again,
Max
