Adprep failure before 2003 upgrade

I have 2 DC's and we have updated one of them from Exch 2000 to Exchange
2003 and that was successful. Then I tried to run adprep /forestprep from
the Windows 2003 Server CD and got the following error.

Adprep was unable to update forest-wide information.

Then [Status/Consequences]

Adprep requires access to existing forest-wide information from the schema
master in order to complete this operation.

I was logged in as Administrator for both updates. Can anyone help?

p.s. This server now takes about 5 minutes to shut down and took less than a
minute before.

David
