6.1.1.2.2.1.2.1.3 RODC NTFRS Connection Object

An RODC NTFRS connection object exists for each RODC in the forest. RODC NTFRS connection objects do not exist for writable DCs. An RODC NTFRS connection object represents a path for File Replication Service (FRS) replication [MS-FRS1] from a source DC to a destination DC; it is not used for directory replication service (DRS) replication [MS-DRSR]. This object is a child of the nTDSDSA object of the destination RODC. See section 6.2 for more information about connection objects.

Each RODC NTFRS connection object has the following attributes:

name: RODC Connection (SYSVOL)

Note On Windows Server 2008 operating system and Windows Server 2008 R2 operating system, the name attribute was set to "RODC Connection (FRS)".

parent: nTDSDSA object

objectClass: nTDSConnection

enabledConnection: TRUE

fromServer: A reference to the nTDSDSA object of the source DC.

schedule: Contains a SCHEDULE structure that specifies the time intervals when replication can be performed between the source and the destination DCs. See section 6.2.2.7 for more information about how this value is derived.

systemFlags: {FLAG_CONFIG_ALLOW_RENAME}

options: Both of the bits from the following diagram. The bits are presented in big-endian byte order.

0	1	2	3	4	5	6	7	8	9	1 0	1	2	3	4	5	6	7	8	9	2 0	1	2	3	4	5	6	7	8	9	3 0	1

X: Unused. Must be zero and ignored.

IG (NTDSCONN_OPT_IS_GENERATED, 0x00000001): The nTDSConnection object was generated by the system, not by a user or administrator directly.

RT (NTDSCONN_OPT_RODC_TOPOLOGY, 0x00000040): The NTDSCONN_OPT_RODC_TOPOLOGY bit in the options attribute indicates whether the connection can be used for DRS replication [MS-DRSR]. When set, the connection MUST be ignored by DRS replication and used only by FRS replication [MS-FRS1]. See section 6.2 and [MS-FRS1] section 3.1.1.8.
