ORA-12545 WHEN CREATING A NEW DATABASE

Dear Gurus , I have a problem.
I have 2 databases on an win2000 machine and want to create the third .
When I try to create a database with Database Conf. Assistant , it creates the service  and before creating datafiles it gives error ORA-12545 and does not create datafiles although I ignore the error..
I can connect to other two databases from both server and clients . But can not create third DB.
 

Why can this be ?
 

Thank you.
