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 not 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

   The name of the infrastructure operations master for the domain will display.

3. On the infrastructure operations master, open the installation media.
4. At a command prompt, change to the \I386 directory of the installation media, and then type:

   adprep /domainprep

5. After the domain preparation data has replicated throughout the domain, upgrade the domain controller by running Windows Server 2003 Setup (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.
