Document the Existing Environment

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

Before upgrading a Windows NT 4.0 domain to Windows Server 2003 Active Directory, document the existing Windows NT 4.0 domain structure.

Create a diagram that includes the following information:

• The names of all account and resource domains.

• The inbound and outbound trust relationships that each domain shares.

If documentation already exists for your domain, review the existing documentation for accuracy and clarity.

Figure 8.3 shows an example of the existing Windows NT 4.0 domain structure for a fictitious company, Trey Research.

In addition to documenting the existing domain structure, document the following:

• The domain controllers and the services that each provides in the domain.

• The existing hardware configuration on all domain controllers in the domain.

• The existing network configuration, including IP address and network adapter information for each domain controller.

• The current domain controller assignments and the role that you plan to assign to each domain controller after the in-place domain upgrade.
