REG_DWORD

1–65,535 ( port number )

(There is no default value for this entry.)

Description

Specifies the port used for Active Directory replication on this server. The RPC locator always returns this port number when queried for the Active Directory replication port for this server.

By default, Active Directory uses a dynamically assigned port to transport replication updates within sites. However, you can use this entry to create a fixed port assignment. This setting is designed for routed environments and those using port filtering.
