1311Directory Service (DC)Replication & DCsCRITLast updated:

KCC cannot build a replication topology

What it means

Sites & Services configuration cannot yield a replication path: a site with no Site Link, or an unassigned subnet.

First steps

  1. 1Open Sites & Services: does every site have a Site Link and at least one DC?
  2. 2Verify every subnet is mapped to a site.
  3. 3Run repadmin /replsummary to find the broken direction.
