My manager wanted to know if we can keep the same IP on the new server and if this was possible. Multi-Master Model A multi-master enabled database, such as the Active Directory, provides the flexibility of allowing changes to occur at any DC in the enterprise, but it also introduces the possibility of conflicts that can potentially lead to problems once the data is replicated to the rest of the enterprise. A FSMO role holder is not the only domain controller that stores accounts and permissions.

Seizing this role to another domain controller is a significant action. After the domain naming master role has been seized, the domain controller that had firectory performing the role cannot be brought back online. Two roles are performed for the entire forest, and two roles are performed by three roles for each domain. One way Windows deals with conflicting updates is by having a conflict resolution algorithm handle discrepancies in values by resolving to the DC to which changes were written last that is, “the last writer wins”while discarding the changes in all other DCs.
In such cases, it is best to prevent the conflict from occurring rather than to try to resolve it after the fact.
Administrators should use extreme caution in seizing FSMO roles. United Kingdom – English. As a result, cross-domain object references in that domain will not be updated and a warning to that effect will be logged on that DC’s event log.
