i have installed BI70 ontop of Windows on Oracle. The installation went fine and the system worked for a few days without any problems.

Now we got the ORA12541 saying the TNS Listener could not be contacted. Our base admin said, its because the SID is AC2 and the database ID is OR2. But i dont want to believe this.

I also configured the tnslistener.ora and got no results.

Does anyone have any idea what i can do?

Thanks in advance.
