Windows Server Active Directory

Windows Server Active Directory

While adding a new Domain Controller (DC) to your pre-existing forest, a nice tip to remember is to:

  • (At the beginning) Always configure your wanna-be (New) DC's TCP/IP v4 PRIMARY DNS IP Address to point it to the FSMO DC.

Then, once the New server becomes a new DC ("gets promoted"):

  • Make sure that replication is successful and it consistently works (ie. when manually solicited).

To manually solicit replication between two DCs, you may use the repadmin command.

Example repadmin command:

repadmin /syncall fsmo-dc01 dc=pwrusr,dc=com /d /e /a

The above command will sync (replicate) your New DC with "fsmo-dc01".

 

Once replication works consistently:

  • Update your New DC's TCP/IP v4 PRIMARY DNS IP Address to point it to itself first (ie. as Primary DNS Server) then to the FSMO-DC after (as a Secondary DNS Server).
