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
