Rollback to NT4 Domain from 2000 mixed mode

Archived from groups: microsoft.public.win2000.active_directory (More info?)

Have corrupt 2000 AD no backups mixed mode with NT4 bdc's. Have 2K & XP
clients.
AD is still online might be able to push policy to turn off Kerberos or
something.

Anyone have a way to rollback to NT4 without having to re-add these clients
to the domain.

Help...

Thanks,

Thank you very much for your response. They have all XP&2000 clients so
trick
is disabling Kerberos and a what ever it is to allow 2k & Xp clients to
authenticate to a rollback nt4 pdc. I don't want to have to readd these to
the NT4 PDC domain.
