Multiple IPs for the same domain controller - MS Supports this? RRS feed

  • Question

  • Hi All,

    We have a setup of mixed DCs, Windows 2016 and Windows 2008R2.

    We are planning to decommission the old 2008R2 DCs and planning to add old DCs IP as additional IP in 2016 DCs.

    What I would like to know is, is this approach supported by Microsoft?

    If in case any issues reported in the future, will Microsoft support our infrastructure with this kind of setup?

    Thank you,

  • Having multiple ip addresses on a domain controller will always cause no end to grief for active directory DNS. I don't see the point? Once the old ones are decommissioned you can simply re-ip the new DCs with the old addresses.
