I'm not sure what either of these has to do with Windows authentication as
it does not use LDAP or WinNT for authentication. Are you doing forms
authentication against AD using LDAP?
In any case, I'd suggest you discover the defaultNamingContext for your
domain again by binding to RootDSE on your domain controller and reading the
defaultNamingContext attribute. This will give you the new domain root.
In general, you should never hard code that in an application but should
always look it up dynamically from RootDSE.
