You probably have a line in you sqlnet.ora file that looks like this:
sqlnet.authentication_services = (NTS)
If so, comment it out with a pound # sign.

Please respond
to ORACLE-L
hai...DBA,
i'm a newcomer for Oracle Enterprise Edition. i used to learn Personal Edition 8.1.6 before.
now i'm facing a problem in Enterprise Edition 8.1.6 on Win2000 Advance
Server.
It worked fine before then suddenly, when i attempt to login,
no matter it's SQLPlus, EMS, DBA Studio,....
it's just returned this error message:
ORA-12638 Credential retrieval failed so i can't login and can't start the oracle.
i referred to Oracle error code description, it say,
Cause: The authentication service failed to retrieve
credentials of a user.
Action: Enable tracing to determine the exact error.
so, what should i do? enable tracing for what? Listener?
thanks and hav a nice day.
