Promote a new DC RRS feed

  • Question

  • Hello, 

    I wanted to deploy an new DC in new branch office in Site 3

    Basically, we have 3 site : Site1, Site2 and Site3

    Site1 and Site2 can communicate

    Site2 and Site3 can communicate

    On site 1 I have DC1 with all FSMO roles and a Exchange Server

    On site 2, I have another DC2 and some servers

    On site 3, i will have a DC3 and Data Server.

    Can I promote an new DC3 on Site 3 even if it can communicate only with DC2 and not with DC1 who hosted all roles ?

    Or i need to enable a communication between Site1 and Site3 ?

    Thanks for you help,

  • Hi

    You can promote a DC on site3. But you have to make sure that in ADSS DC2 should be replicating partner of DC3 , so that the AD data can be replicated correctly to all the DCs, else there will be Lingering objects which will cause issue with the domain trust and validation.

    Since DC2 is communicating and replicating with DC1 , so when DC3 will replicate with DC2 then all the data of DC1 will automatically replicate to DC2.

    Also it will be good if you enable communication and replication between Site 1 and Site 3. Also you can create a bridge-head server which is the best option to replicate information and data between sites.
