 Hello, we had to change the NT-Service User of the Oracle Service. Old and new user are domain administrators and local admins and in dba group.
Since the change was made, rman is unable to connect to the database:

C:\Documents and Settings\oracle>rman target / (same with "rman target username/password")

Any connections with sqlplus work fine.


Has anybody an idea?
