    Question

  • Hi,

     

    Is there any issue running ADPREP / forest prep + ADPREP /Domainprep during businesshours, when people are working ?
    Or is it preffered to run ADPREP offhours?

    Thank you.

  • HI,

     

    you can do this without any services disruption during business hours. If you are doing ADPREP for 2008 R2 ensure that you run appropriate adprep version.

     

    If you have 32bit environment then you need to run

     

    adprep32 /forestprep /rodcprep

    on your Schema Master

    and

    adprep32 /domainprep /gpprep

    on your Infrastructure master

     

    if you have 64bit DC(s) then you need to run

    adprep /forestprep /rodcprep

    adprep /domainprep /gpprep

    on the same FSMO holders as above

     

    Running on DC in command-line

    netdom query fsmo

    will help you identify servers holding those FSMO roles.

  • After completing the forestprep check the schema version and wait for the completeing the replication and then run the domainprep.

     

    How to check the schema version.

    http://support.microsoft.com/kb/556086

     

    Schema version for new operation system

    Find the Schema version for the operating systems


    13 - Windows 2000 Server
    30 - Windows Server 2003 RTM, Windows 2003 With Service Pack 1, Windows 2003 With Service Pack 2
    31 -Windows Server 2003 R2
    44 - Windows Server 2008 RTM
    47 - Windows Server 2008 R2

    ________________________________

    Take the system state backup of your schema master then disable the outbound replication and run the forestprep.

    Repadmin /options <dc-fqdn> +DISABLE_OUTBOUND_REPL

    After getting the success log enable the out bound replication via repadmin.

    Repadmin /options <dc-fqdn> -DISABLE_OUTBOUND_REPL

    wait for competeing the replication.

  • Hello,

    it can be run during business hours. Keep in mind that the schema changes are replicated forest wide. If you have slow links to the DCs then the better option can be to run the commands at COB.

  • No,it will add new schema attribute & classes & will replicate the other domain controller,but that depends on no of domain controller you have,scheduled replication time is it after every 15min or so, but consider taking backup prior running the command & if you replication is schedule in every 15min, can be extra traffic to replicate the changes to other dc.
