Your network consists of one Active Directory forest that contains two domains.
All domain controllers run Windows Server 2003.
The network contains file servers that run Windows Server 2003 R2.
The files servers run DFS Replication.
The forest root domain is named contoso.com and the child domain is named corp.contoso.com.
You prepare the forest schema for the installation of domain controllers that run Windows Server 2008.
You prepare the corp.contoso.com domain. You install a new domain controller that runs Windows Server 2008 on corp.contoso.com.
You need to plan an Active Directory implementation to meet the following requirements:
- Enable DFS Replication support for SYSVOL on corp.contoso.com.
- Allow the installation of new domain controllers that run Windows Server 2003 in the forest root domain.
What should you include in your plan?
A. Upgrade all file servers to Windows Server 2008.
B. Run adprep /domainprep /gpprep on the corp.contoso.com domain and run adprep /domainprep on the contoso.com domain.
C. Upgrade all Windows Server 2003 domain controllers to Windows Server 2008. Raise the functional level of the forest to Windows Server 2008.
D. Upgrade the Windows Server 2003 domain controllers in corp.contoso.com to Windows Server 2008. Raise the corp.contoso.com domain functional level to Windows Server 2008.
