When attempting to change from mixed mode to native mode it states that it
happened successfully and that it could take some time to propagate etc.,
however a subsequent message states either, a.) The following active
directory error occurred: a device attached to the system is not
functioning, or b.) The following active directory error occurred: A global
group cannot have a universal group as a member. Then if I go back into the
properties for the domain it shows mixed mode, the change never takes. Any
ideas or suggestions would be very welcome. Please reply to this post.

Thanks,

Alan

I assume all your DCs are Windows 2000 and higher?
Can you check Enterprise Admins and Schema Admins group, which groups they
are members of?
