I have an application that uses Windows 2000 domain user accounts to login. The domain accounts were in a child domain that is no longer connected to the parent domain. And the primary domain controller of the child domain went up in smoke, so the back up dc from the child domain is the only dc for the application to validate it's users, but no users can logon to the application. The application server and the dc are connected to each other through a switch, are on the same subnet and the same domain. they ping each other as well as resolve dns. I am missing something but I don't know what. PLEASE help.
