Change your Active Directory Site Links to Change Based Replication

In special situations or if you have large amounts of bandwidth between sites, you can change the replication frequency between sites to match the replication between servers in the same site. The steps below show how to enable this. Keep in mind however, that there will no longer be any compression between your sites so you will be increasing you AD replication traffic by about 20-30%.

To enable change notification between sites

  1.. In ADSI Edit, expand the Configuration container.
  2.. Navigate to the Inter-Site Transports container, and select CN=IP.
      (You cannot enable change notification for SMTP links.)
  3.. Right-click the site link object for the sites for which you want to
       enable change notification, and then click Properties.
  4.. In the Select a property to view box, select options.
  5.. In the Edit Attribute box, if the Value(s) box shows <not set>, type 1
       in the Edit Attribute box. If the Value(s) box contains a value, you must
       derive the new value by using a Boolean BITWISE-OR calculation on the old
       value, as follows: old_value BITWISE-OR 1. For example, if the value in the
       Value(s) box is 2, calculate 0010 OR 0001 to equal 0011. Type the integer
        value of the result in the Edit Attribute box; for this example, the value
        is 3.
  6.. Click OK.

Enabling change notifications across site links propagates all change
notifications. With change notification between sites set, changes propagate
to the remote site with the same frequency that they are propagated within
the source site, including changes that warrant urgent replication.

Note Do not enable change notification on demand-dial IP site links or on
SMTP site links.
