SharePoint User Group UK

Hi All,

We have a SharePoint MOSS 2007 installation which has two different external hostnames. When inspecting the setup I've noticed that there are two Alternate Access Mapping Collections mapped to the same web application. Each AAM collection contains one url mapped to the default zone.

I can't see how AAM collections are mapped to web apps or even how to create a new AAM collection. I've always thought that there was just a one to one mapping between web apps and AAM collections.

Does anyone have any idea as to how you would create such a situation?

Cheers Russell

Hi Russell,

It sounds like your web application has been extended and not just another URL added under Application Access Mappings.

Steve

The fact that the web application hadn't been extended was the issue.

This can be caused by having "External Resource Mapping" entries in the AAM section, in my case it was not the cause of the problem.

A discussion of how I came to this conclusion is here...

and an full explanation of our specific issue and the fix is here...

Thanks for your response anyway. :-)
