I get the error "The tag is invalid" when I try to open the NT user manager now that I have upgraded to Samba 2.2.1 on a Redhat 7.0 Box. Samba is configured as a PDC and everything worked until I upgraded Samba. I have searched the news groups and there are other people with the same problem but no one has a solution. This is a pretty big problem for me because on a member server in the domain I have Exchange server running and I cant add users to exchange because I cant get a list of users on the domain now I only get this error. Thank you for you help. Forrest Dickinson
