Sorry for the cross posting:

We have joined our SPPS 2001 server to Active Directory as a member server.
However, there is still a TRUST will the NT 4 Domain because not all of the
users have been migrated to AD yet.

The problem is that users can access the portal via their NT 4 Domain user
name and password. The external portal is configured for Basic
Authentication and users cannot access the external portal using their
Active Directory user name and password.

I've added the Active Directory Domain Users group to the local Users Group
on the portal server but still no luck.

Any ideas??
