'Schema may be modified on this Domain Controller' gray

[John Adkison]

In the Schema Management snap-in, when I right-click and
select properties to determine the schema master, the
check box for "Schema may be modified on this Domain
Controller" is grayed-out. I am logged on as
Administrator, with Schema Admin privileges, on the actual
server that is the Schema master. This is a one-domain
controller domain.

I've seen this problem before, but it usually clears-up on
its own with a little time. I assume there is something
running in the background that causes that. But, in this
case, the problem is not going away.

although it means that you'll be using a registry hack rather than the
console to enable schema changes.

The registry already shows that it is enabled. However,
when doing ForestPrep for Exchange 2000, I'm told I do not
have the permissions or Active Directory is too busy.
