  • Adprep /Forestprep Error

    Hello,
    I have a Windows 2000 domain, all running SP4. (No exchange Server)
    I logged into the DC with Schema master role with all the privileges ( Schema Admin, Enterprise Admin, Domain Admin). Disabled anti virus software and executed Adprep /Forestprep from local hard disk as a preparation for 2008 R2 migration.

    After sometime I got the following error
    -------------------------------------------------
    The command has completed successfully
    Connecting to "XXXXXXX"
    Logging in as current user using SSPI
    Importing directory from file "C:\WINNT\system32\sch41.ldf"

    An error has occurred in the program

    ectory for detailed information.

    [Status/Consequence]
    Adprep requires access to existing forest-wide information from the schema maste
    r in order to complete this operation.

    Check the log file, ADPrep.log, in the C:\WINNT\debug\adprep\logs\20100604160119

    Schupr.log says

    If the error is "Insufficient Rights" (Ldap error code 50), please make sure the current logged on user has rights to read/write objects in the schema and configuration containers, or log off and log in as an user with these rights and rerun schupgr.exe.
    ------------------------------------------------------------------------
    What is causing this?
    Now how can I proceed?
    Do I need to restore the system state and rerun the command?
    Is there going to be any problems for end users?

    Appreciate a quick reply

    Hi,

    We had a simular issue at one point when upgrading from 2000 domain to 2003 and this was because of mangled objects in ad which were caused by exchange 2000 schema updates. I know you state that you do not use exchange and my org didnt use exchange 2000 either; however someone got it in there head along time ago to install exchange 2000 and prepped the forest; however the implementation did not go any further.

    It is worth checking the following in ad to see if the attributes do exist. I know you are upgrading to 2008 so this might not even apply but it is worth checking.

    http://support.microsoft.com/kb/325379

    Scroll to the section outlined below.

    Scenario 2: Exchange 2000 schema changes will be installed before the Windows Server 2003 adprep /forestprep command


    Regards,

    Jamie

        I can't quite tell from his post if he is installing 2008 R2 onto the current server and upgrading, or transitioning to a new server.. ?

        My suggestion, (and i may have missed the info in the op) is to ensure you are logged on as the DA account before running Adprep

        It may also be worth doing the 2003, then the 2008 adprep in order.. just to see if it helps

          A couple of things to consider:
          Run the 32 bit version ADprep32.exe (though you might've already done that)
          Also for /forestprep you need Enterprise Admin credentials.

            I am running the adprep32.exe from Windows 2008 DVD with Schema Admin/Domain Admin and Enterprise Admin role.

            I will rerun the tool again this weekend after setting the registry value "Schema Update Allowed = 1"

              I have executed the command adprep /forestprep again with the modifications to the registry to allow schema updates and the schema was updated successfully.

              Thank You.
