After each additional domain controller is deployed, verify that the upgrade was successful. Use the same tests and tools that you used to verify that the upgrade of the Windows NT 4.0 PDC was successful. For more information about developing a test plan, see "Develop a Test Plan" earlier in this chapter.

Also verify that DNS recursive name resolution is configured according to your organization’s DNS design. For more information about verifying recursive name resolution, see "Verify DNS Server Recursive Name Resolution on the First Forest Root Domain Controller" earlier in this chapter.
