adprep /domainprep error


EMI Computer

I am trying to upgrade my w2K DC to w2k3. adprep /forestprep ran fine,
but adprep /domainprep fails. The DC is the schema, operations and
infrastructure master.

See exerpt from log file:

Adprep was unable to modify the security descriptor on object


ADPREP was unable to merge the existing security descriptor with the
new access control entry (ACE).

Error code: 0x0. Server extended error code: 0x0, Server error message:

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