I have a SharePoint farm with two WFEs. I have 1 web app with anonymous access enabled and windows authentication and 1 site collection within the web app. I have extended the web app to internet zone using same windows auth mechanism and anonymous access to enable calls coming in on two different hostnames (abc123.com and www.abc123.com) using alternate access mapping.
When I access the original web app url (abc123.com) via either WFE it works fine When I access the extended web app url (www.abc123.com) on one box it redirects to /pages/default.aspx and works fine on the other WFE it fails with a 404 and doesnt redirect.
Any ideas what the problem could be or areas I could check? Cheers Russell
