Hi All,

I have rare problem, i have Test DB as defualt DB.
When i connect using IPC Protocol/Beq Session i am getting the error as under....

SQL> conn
Enter user-name: sys as sysdba
Enter password:
ERROR:
ORA-12560: TNS:-protocol adapter error

Warning: You are no longer connected to ORACLE.


Where as if i connect thru TCP/IP Protocol it works fine.


SQL> conn sys@test as sysdba
Enter password:
Connected.


Am using Win NTS authentication in SQL * Net
Has somthing gone wrong in OS IPC protocol level?????
Please help.....

Abhay.
