We have several trust established between our domain and others. The question has been asked as to what server is a user authenticating against when logging into a trusted domain? In other words; say you have Domain A and Domain B. Domain A is in Dallas and Domain B is in Ft. Worth. There is a two way trust established. A user in Dallas is logging into Domain B from thier workstation- Does the users credentials go to the DC in Dallas then get passed to the DC in Ft. Worth or does it bypass the DC in Dallas and goes straight to the DC in Ft. Worth?
