Error Upgrading Windows 2003 Schema to Windows 2008 Schema

Discussion in 'Server Setup' started by Megan Kielman, May 21, 2009.

  1. All -

    We using the command 'adprep /forestprep' to update our WIndows 2003 R2 (Rev
    31) schema to WIndows 2008 (rev. 44), we are getting the following error:

    ERROR: Waiting for ldifde to complete failed: 6

    However, the result of the command stated the forestprep was successful. We
    went ahead and attempted to perform a domain prep but were unsuccessful. When
    we investigated closer, we found the forestprep was failing when attempting
    to import sch32.ldf. When we performed the import of that file manually we
    received the following error:

    Entry DN: CN=Top,CN=Schema,CN=Configuration,DC=dev,DC=corp,DC=dom
    Add error on line 217: Unwilling To Perform

    The server side error is "An attempt is made to modify the base schema."

    An error has occurred in the program


    Any suggestions?

  2. Hello Megan,

    You run the adprep command from the 2008 installation disk directly or did
    you copy the adprep folder to harddisk before? I assume you use an account
    that is member of the schema admins and run it on the schema master?

    Best regards

  3. We copied sources\adprep directory locally. We have also confirmed we are in
    the correct groups, Enterprise and Schema Admins and we were on the Schema
    Master. Do you have thoughts as to why this failed?

  4. Hello Megan,

    Run the command from the installation disk, not form the copied folder on
    the disk.

    Best regards

  5. We just tried it directly from the CD and received the following output.

    D:\sources\adprep>adprep /forestprep

  6. Hello Megan,

    Assuming that you run an AntiVirus program on it, at least stop all services
    belonging to it and try again.

  7. Same error. Do you know what the error code '6' means? Any ideas where we
    might find this information?

  8. Hello Megan,

    Please check if all 5 FSMO roles are exsiting, run "netdom query fsmo" and
    check that they are lsited on existing DC's. Additional run dcdiag /v on
    the 2003 DC's and post theb output if errors exist.

    Best regards

  9. Hi again -

    All 5 roles are hosted by the same DC. I also ran dcdiag /v and no errors
    were posted.

    Other suggestions?

  10. Hello Megan,

    Have a look on this one about Exchange and Unix:
