  • unable to run forestprep for exchange 2003

    i am having trouble with installing exchange 2003. when i run forestprep it gives me this message:

    to install the first exchange server in a domain, or to setup in forestprep mode you must be in exchange full administrator at the organization level.

    i have tried every thing but still i can not pass this message.

    i have checked permissions for the administrator to verify in which group it belongs and found these groups which seems to be ok

    administrators group
    debugger users
    domain admins
    domain users
    enterprise admins
    exchage domain servers
    exchange services
    schema admins

    i dont know what i am missing here

    i am using win2003 enterprise.

    Are you getting any errors in the event viewer? How many DCs do you have? See if the Schema Master owner DC is online and accessible.

      Install the Windows Support Tools from the Windows CD or download from Microsoft.

      Then run

      netdom query fsmo

      Ensure that all servers listed are live.

      Next, run the DCDIAG and other tests that are indicated on the Exchange server auto play menu to confirm that everything works correctly.

      Finally - has Exchange been installed on this domain/forest before? I have seen that error when there are dregs of a previous Exchange installation in the forest/domain. Installing the system management tools ONLY allowed me to see the remains and set the permissions correct at the Org level.
