When using SharePoint with a proxy server such as ISA, you will need to configure SharePoint Alternate Access Mappings (AAM) if the external address and the internal address are different. For example, if your internal address is http://wssserver/ and your external address is http://wssserver.domainname.com/. Here is a simple guide to configuring AAM on MOSS or WSS Server.

- Open up your SharePoint Central Administration on the server running SharePoint.
- Navigate to Operations under Central Administration.
- Open up Alternate access mappings under Global Configuration
- Click Edit Public URLs
- Select your Alternate Access Mapping Collection (your web application)
- Then enter the respective URLs that the application will be accessed via.
- I usually do an iisreset /noforce after this.
I found that the other tutorials on the internet wern’t straight to the point, and it was hard to understand them. Hopefully this clears things up for Sharepoint novices out there!
