  • Error message prepare AD for 2003 r2

    I am trying to upgrade our domain controllers to windows 2003 r2. We have 2 domain controllers running windows 2003 sp2 with latest updates, 1 exchange server 2003 again fully service pack with latest updates.
    when I try to run adprep /forestprep on the master DC from windows 2003 r2 disk2 I get the following error
    "attributeSyntax" attribute value for objects defined in Windows 2000 schema and
    extended schema do not match.
    A previous schema extension has defined the attribute value as "" for obj
    ect "CN=preferredLanguage,CN=Schema,CN=Configuration,D C=,DC=,DC=" differ
    ently than the schema extension needed for Windows 2003 server .
    Adprep cannot extend your existing schema
    [User Action]
    Contact the vendor of the application that previously extended the schema to res
    olve the inconsistency. Then run adprep again."

    I have already tried the hotfix KB919938 with no luck. Can some help / point me the right direction? Thanks

    I had a similar issue and we took it up with MS. We got an ldf file from MS and we had to import that prior to ADPREP.

    Bad luck that I do not have that .ldf with me right now.
