15.4. Upgrading from Windows 2000 to Windows Server 2003
Problem
You want to upgrade your existing Windows 2000 Active Directory domain controllers to Windows Server 2003. Before doing this, you must run the ADPrep tool, which extends the schema and adds several objects in Active Directory that are necessary for new features and enhancements.
Solution
First, run the following command on the Schema FSMO domain
controller with the credentials of an account that is in both the
Enterprise
Admins
and Schema
Admins
groups:
> adprep /forestprep
After the updates from /forestprep
have replicated throughout the
forest, run the following command on the Infrastructure FSMO domain
controller in each domain with the credentials of an account in the
Domain
Admins
group:
> adprep /domainprep
If the updates from /forestprep
have not replicated to at least
the Infrastructure FSMO servers in each domain, an error will be
returned when running /domainprep
.
To debug any problems you encounter, see the ADPrep log files located
at %SystemRoot%\System32\Debug\Adprep\Logs.
Tip
adprep can be found in the \i386 directory on the Windows Server 2003 CD. The tool relies on several files in that directory, so you cannot simply copy that file out to a server and run it. You must run it either from a CD or from a location where the entire directory has been copied.
To determine if adprep
/domainprep
completed, check for the existence of the
following object, where <DomainDN>
is
the distinguished name of the domain:
cn=Windows2003Update,cn=DomainUpdates,cn=System, ...
