3.3.2.1.1 SYSVOL Connection ScheduleTimer

FRS MUST replicate SYSVOL using the same intra-site connection objects and schedule (section 2.3.2.4) built by the DRSR, as specified in [MS-DRSR], for Active Directory replication.

FRS uses two types of replication schedules for SYSVOL:

  • SYSVOL connection within a site. The connection is always considered to be on; any schedule MUST be ignored and the changed files replicated immediately.

  • SYSVOL connection between sites. SYSVOL replication is initiated between two inter-site members at the start of the 15-minute interval, assuming the schedule is open. The connection MUST be using a trigger schedule. When a triggering schedule is used, the upstream partner ignores its schedule and responds to any request by the downstream partner. When the schedule closes, the upstream partner unjoins the connection only after the current contents of the outbound log, at the time of join, have been sent and acknowledged. The SYSVOL replication schedule can be configured so that replication takes place four, two, one, or zero times per hour:

    • When set to four times per hour, replication MUST start at 0:00, 0:15, 0:30, and 0:45. This schedule is essentially continuous replication. 0:00 means exactly on the hour.

    •  When set to two times per hour, replication MUST occur at 15-minute intervals starting at 0:15 and 0:45.

    •  When set to one time per hour, replication MUST start at 0:00 and ends at 0:15.

    •  When set to zero times per hour, replication MUST NOT start.
