As do I.  In all of my configs, it was a requirement for basic 
authentication to work- Basic authenticaion is Logon Type 2, which requires 
"log on locally" rights.   The thread started when JD could not get 
internal folks to access OWA via the FQDN- however, they could access via 
the NetBIOS name.  In his config, he has Basic and NT Integrated selected, 
but says his users are *not* members of a group that can log on locally, 
yet it still works, so I am thinking that internal clients are using NT 
Integrated.

However, I have not heard back from him whether his internal clients have 
to enter a password or not, so I don't know.

I think it is one of two things:  One, he is using NT Integrated 
internally, which is Logon Type 3 (or a "network logon") which does not 
need "log on locally" rights, but is failing because he done not have the 
FQDN in his Intranet Sites and/or "Logon automatically only in the Intranet 
Zone" is not set.  In this case, I think it is then falling back to Basic 
Authentication, which fails because they can't log on locally.

The only strange part is that his external people can use it, and he says 
they log in, which means it is basic authentication, which means they have 
to be set for "log on locally."

It is a mystery!  We'll see what the deal is when he posts back.

Thanks!
