  • How to remove automatically generated Replication links to all the Dcs

    We did set up an Additional domain controller w2k3 in a existing domain. The dc is also a Dns server. Once Ad was installed i created a new Site in in Active directory sites and services and assigned it an Unique subnet and moved the Dc into the Site.

    It is not a GC at this point. Once the replication was done KCC picked up all the dc's under the site link to replicate from /to this new DC.

    Before this new DC all the replication was done to say server -1, but now this dc has added it self to all Dc. In short it is replicating from all the dc's and replicating to all the dc's.

    is their a way i can avoid this and just point the new dc to replicate to Server-1 as it used to be with all Dc before this new install?

    Any insight will be appreciated.

    Many Thanks

    How many Site Links do you have? If you have all your Sites in one Site Link then KCC will build a mesh.

      Garen,

      Thanks for your Quick reply. We do have 10 Site links but But the dc's in different sites are under/Using one site link. Replication between these Dc's under different sites was limited to one Dc. after adding this additional Dc it sarted replicating to all the dc in different sites using same site link it also get replicated from all these dcs.
      I tried deleting the automatically generated replication links but they cme up after 15 mins

        Why do you want to remove those Autmatically generated replication links?
        Usually it's a good practice to let them live.

          I do agree that it is generally suggested to go with KCC genarated links.

          This New Dc was for one of our remote offices which is on T1 line. and more over i do not see any point why this new dc should be getting replication data from all the 10 dc's in different Sites.

            But usually all DC's contain the same data (if not I should be worried ) so if your replication partner DC fails the new DC can still replicate with other DC's

              So you say that Traffic /bandwidth should not be a problem with the DC replication partner is one dc or Ten dc's?

                IIRC The replication traffic with Windows 2003 and up is drastically reduced if the forest is in Windows 2003.
                It will only be triggered by and update and it will use the fastest link first.

                However I don't know how your Forest look like and how your WAN looks like. It might help if you create a drawing.

                  If traffic does become an issue then you can re-configure the bridgehead servers to only replicate out of hours. I wouldn't bother though unless it is causing performance issues.

                  We've got a customer replicating across 8 sites on 2mb ADSL connections with no issues. For the sake of redundancy I'd stick with things as they are.
