Examination of the Dcpromoui.log file indicates that the initial part of the promotion was successful (this is also verified because the computer becomes a member server in the domain), but that the promotion to domain controller did not succeed because Dcpromo.exe could not modify the machine account.
- In the Active Directory Users and Computers snap-in, edit the Default Domain Controllers Policy on the Domain Controllers Organizational Unit.
- Double-click Computer Configuration, click Windows Settings, click Security Settings, click Local Policies, and then click User Rights Assignment.
- Under Enable Computer and User Accounts to be trusted for Delegation, add the appropriate account or group.
- Apply the policy using one of the following methods:
- If it is a Windows 2000 domain controller, open a command prompt, and then type: secedit /refreshpolicy machine_policy /enforce
- If it is a Windows Server 2003 or a Windows Server 2008 domain controller, open a command prompt, and type: gpupdate /force
- If it is a Windows 2000 domain controller, open a command prompt, and then type:
- Force replication from the domain controller on which the policy was changed to the other domain controllers in the domain by using repadmin, replmon, or Active Directory Sites and Services.
