I have a Sharepoint 2003 Portal Server. When someone from the local
domain logs into the site (domain\username), there are no problems. If
someone from another child domain (trust is already verified) tries to
authenticate, the authentication box just keeps coming back.
Eventually, you get an HTTP error 401.3 unauthorized page. The odd
part is this - if I put the users account into the local
servers "users" group, the person can get in using domain\username.
What am I missing??
