I am in the setup stages of the Upgrade, and it does the check of the
system.  I am logged in as the administrator, but when it checks it won't
let me go ahead because it says that "You must be a member of the Domain
Admins; Schema Admins and Enterprise Admins groups"

I checked the account and sure enough I am a member of these groups.  I
tried creating another admin account with group memberships in these groups,
but when I try to run the setup again it tells me you have to be logged in
as the administrator.

Any ideas???

Thanks in advance.
