i am trying to upgrade the windows 2000 domain to 2003 and have decided to follow the method where a 2003 member server is upgraded to a domain controller, thereby converting the domain to 2003, after which I can upgrade the 2000 servers in place.
I have successfully installed the InetOrgPerson LDAP fix
I have successfuly run the adprep/forestprep as well as the domainprep without error and from the 2003 CD kit
DCDIAG shows no errors
ADSI edit shows the objects indicating a forest upgrade
if i attempt to rerun the adprep command, i get an error telling me that the domain schema has already been extended.
I have 2 Domain controllers, 1 Exchange 2000 server, several member servers. All 2000 servers running SP4. The primary domain controller is the operations master, schema master, etc. Replication has taken place between both servers, without error.
at one time, very long ago, this was an NT4.0 domain which was upgraded to 2000. the original domain controllers have long since been retired from service. The domain is running in Native Mode.
the 2003 server is R2 Enterprise.
when the DCPROMO wizard runs, it completes with the error:
The Active Directory Installation Wizard cannot continue because the forest is not prepared for installing Windows Server 2003. Use the adprep command-line tool to prepare the forest and the domain.
This version of the Active Directory schema of the source forest is not compatible with the version of Active Directory on this computer
