Cannot add a Windows 2003 server to a Windows 2000 domain
Posted on 2006-06-27
I am trying to promote a windows 2003 member server to a Domain controller in a Windows 2000 domain environment.
This is how it is configured.
We have two offices connected over a adsl VPN link.
The server configurations are listed below
Windows 2000 domain controller with Exchange 2003 server installed on it
Windows 2003 member server (want to promote to DC)
Windows 2000 domain controller with Exchange 2003 installed on it
I ran adprep /forestprep on Primary DC
I ran adprep /domainprep on Primary DC
I tried to run the commands on other domain controller after I had issues, but it said it has already ran.
I went to sites and services and clicked on the NTDS settings and said replicate now to make sure that replication has taken place.
I ran dcdiag without any switches and everything passed on both servers
I keep on getting the error on my Windows 2003 server:
The operation failed because:
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 both the forest and the domain. For more information about using the Adprep, see Active Directory Help.
"The version of the Active Directory schema of the source forest is not compatible with the version of Active Directory on this computer."
I have waited 1/2 hour and still no go
