Do custom AD schema changes replicate to other DC in the forest or need to be manually configured on each DC? We Will be adding a custom object class and AD is hosted on server 2012 R2 & 2016 servers. Have more than 5 servers. Will a reboot update the Ad servers?

    Hi @Tech Santosh

    Yes the changes need to made on the DC that hosts the schema master role, you don't need to reboot the DCs or any of the member servers connected to the domain.

    If you are creating a custom LDF file for the schema update, either add the lines below to the bottom of the file, or use the menu option in the schema console to reload the schema, which will cause the cached schema to be refreshed. The new changes won't be available until you completed this step or after the automatic refresh period, which I think is something like 30 or 60 minutes.

    dn:  
    changetype: modify  
    add: schemaUpdateNow  
    schemaUpdateNow: 1  
    -  
    

    Gary.

    No reboot required.

    As @Anonymous said, the schema partition is forest wide and will be replicated with AD replication automatically

    Hi,

    Hence we can conclude that the changes need to be done on the AD server hosting the schema role & post the changes the other servers need to be rebooted.

    Thanks!!!
