| Description | The replication topology update task terminated abnormally with code e0010001. |
| Event Information | According to Microsoft: One of the operations that takes place during the promotion of a replica domain controller is the modification of the UserAccountControl attribute for the computer you are promoting. The UserAccountControl attribute is important for defining the role of the computer as a member server or domain controller. Specifically, the computer you are promoting performs the following tasks: 1. Performs a Lightweight Directory Access Protocol (LDAP) search against an existing domain controller in the domain for its computer account (ObjectClass=user,ObjectClass=computer,SamAccountName=%ComputerName%$). 2. Attempts to update the UserAccountControl attribute, indicating a change from a member server to a domain controller. 3. Attempts to move the computer account object from the current container or organizational unit, to the domain controllers organizational unit of the domain. 4. Sources the schema, configuration, and domain naming contexts for replication from domain controllers that already exist. |
