Configure the Site Link Interval to Identify How Often Replication Polling Can Occur During the Schedule Window

Applies To: Windows Server 2008, Windows Server 2008 R2

Bridgehead servers initiate intersite replication by polling their replication partners. You configure the polling schedule on the site link object in Active Directory Domain Services (AD DS). You can use this procedure and the properties on the site link object to determine how often during the available replication schedule you want bridgehead servers to poll their intersite replication partners for changes. Obtain the interval value from your design team.


Intersite connection objects also have a schedule; they inherit their schedule and interval from the site link object.
