MOSS 2007 – Alternate Access Mapping authentication fails
Written by Sam McGeownThis article is now 16 years old! It is highly likely that this information is out of date and the author will have completely forgotten about it. Please take care when following any guidance to ensure you have up-to-date recommendations.
If you have an Alternate Access Mapping configured for a MOSS 2007 site with Integrated Authentication you might find that you get prompted for the DOMAIN\UserName and Password. After 3 attempts you get to a HTTP 401 error.
This can be resolved by following the steps in MS KB 896861
