Need help in trying to determine why after converting 5 DC's to 2008 R2 and the last one was the PDC from 2003, Domain level still at 2003, a file share in another trusted forest which was accessable by IP address\sharename before the last server PDC was converted is now continually prompting for a login and and will not allow the user to pass. Other forest still running 2003 DC's. Domain Trust is still verfiable.
Thanks
Marc
