    TNS-12560 when creating db

    Hi,

    i got a strange problem with my oracle 10g installation on my windows 2008 server.
    the first installation went fine, i could create the database and everything went fine.
    later we upgraded the server to be the domain controller in our domain.
    after this i everything still went fine,
    but when i deleted the database and tried to create another database in dbca i got the TNS-12560: TNSrotocol adapter error and no database was created.
    i tried pretty much everything i could find to dissolve the error, but nothing worked.
    i tried a fresh installation, but got the same error.
    even when i tried to install the example database during the installation dialouge, the installer brings up the TNS-12560 error when it tries to create the database.

    maybe it is not an oracle problem but a windows/networking problem but i just dont get it.
    i hope someone can help me

    greetings,
    stefan

    Did the domain name change? I think you need to go through everything and make sure that things are really set up the way that you think they should be.

    Well if you specify nt_authentication in the sqlnet.ora file you might see this behavior. What is in you sqlnet.ora file?

    Applies to:
    Oracle Server - Enterprise Edition - Version: 10.2.0.3 to 11.1.0.6


    Symptoms
    Install Oracle 10.2.0.3 (Vista/2008 version) on Windows 2008 Active Directory Controller.

    When trying to create the database, around 2% completion, the error ORA-12560 will occur.



    This Problem does NOT reproduce on a Member server. Only the Active Directory Controller.

    Cause
    This is currently logged as Bug 7263061.

    Solution
    Currently, the only workaround is to Install the software on a Non-Controller machine.

    You can try demoting the Controller machine to a Member machine.

    Perform the install, create the database.

    When everything is setup correctly, you can promote the machine back to a Controller.

    However, be aware you may have to go through these steps whenever you create a new DB.
