A built-in group on all servers and workstations running Microsoft Windows NT. The Replicator group is used by the Directory Replicator Service to replicate part of the file system between computers running Windows NT.
The group’s membership is initially empty. When you configure the Directory Replicator Service, you must create a special user account with any name to provide a context in which the service can start up and run. You must make this account a member of the Replicator, Backup Operators, and Domain Users groups.
The Replicator group must also have change permission for the Export and Import folders on the computers involved in replication and must be granted the system right called Logon As A Service using User Manager for Domains in order for replication to function properly.
