Adding 2019 DC to SBS 2011 Domain RRS feed

  • Question

  • Hi All,

    I am wanting to promote a 2019 server to an existing 2011 Domain to provide DNS at a remote site, after trying to promote I am given the following message.

    Verification of replica failed. The forest functional level is not supported. To install a windows 2019 domain or domain controller, the forest functional level must be Windows server 2008 or higher.

    Is what I am trying to do the correct actions to achieve DNS at the remote site, ie create the server as a DC, or should this be done in another way. There are no plans at present to retire the SBS Server.

    Regards

    Richard

  • HI
    site A: sbs2011 DC integer DNS 
       ip address :                   10.106.1.10
        subnet:                       255.255.255.0
        default gateway:        10.106.1.1
        preferred DNS server: 10.106.1.10
        alternate DNS server: 177.122.57.33 (isp DNS )
    routerA: 10.106.1.1

    site B:server 2019 standard only DNS
       ip address :                   10.109.1.10
        subnet:                       255.255.255.0
        default gateway:        10.109.1.1
        preferred DNS server: 10.106.1.10
        alternate DNS server: 10.109.1.10 
    routerB: 10.109.1.1
    "Am I better of setting this up at HQ then moving the server to the remote site and changing the IP tp the local subnet?"
    3.No,for example, siteA and siteB have been connected by MPLS,so that computers in siteB can communicate with computers(include DC) in site A.you need to move your server to site B first and config static ip for w2019 in siteB.Finally ,we can add w2019 to SBS2011 domain and configure it as second DNS server.

  • Richard,

    You need to raise Forest and Domain Functional level to Windows Server 2008 R2. That can be done on a SBS 2011 but there is more. Before you can install a 2019 replica Domain Controller you must migrate FRS to DFSR.

    As you tried to add a replica and it failed I suggest you remove the ADDS role from that 2019 server and clean up anything left on the SBS 2011.

    You can add the 2019 as a replica DC after Forest and Domain Functional level has been raised and FRS has been migrated to DFSR.

  • Thanks for your replies,

    I took "Andy YOU" answer and all seems to be well. This DNS was required as if HQ went down then remote would loose internet, any suggestions on the correct DNS settings for fowarders etc.

    Regards

    Rich

  • It is fundamentally wrong if you set Network adapters of Domain joined devices to anything else then Active Directory integrated DNS servers. If you do add DNS servers that have no knowledge about your Active Directory you will cause replication problems during a migration.

  • HI
    yes,we need to keep synchronized DNS record between Primary DNS and Second DNS, so that when primary DNS server down, the second DNS can work fine.
