Setup has detected that the Active Directory domain needs to be prepared for Windows Server 2003.

Description

• The domain is prepared by using the adprep command on the infrastructure operations master.
• This domain controller is the infrastructure operations master for this domain.

To prepare an Active Directory domain for Windows Server 2003

1. To exit Setup, click Next, click Finish, and then click Exit.
2. At a command prompt, change to the \I386 directory on the installation media, and then type:

   adprep /domainprep

3. After the domain preparation data has replicated throughout the domain, upgrade the domain controller by running Windows Server 2003 (I386\winnt32.exe on the installation media).

Notes

• You cannot upgrade domain controllers in a forest without first preparing the forest and domains by using adprep on the schema and infrastructure operations masters, respectively.
• Depending on the replication schedule for your organization, the time it takes to propagate preparation data will vary.
