Hello..

I'm receiving he following error when connecting to Oracle 9i using OO4O

ORA-24327: need explicit attach before authenticating a user

The most strange thing is that this error occures suddenly, after some time of working with no problems.

The error is magically solved itself after some time. While it is in non-working state I rebooted the machine but without sucess.

This is the SQLNET.ORA file, if this helps:

SQLNET.AUTHENTICATION_SERVICES= (NONE)
NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)

Finally, I tell you that this problem only occurs in a Windows Server 2003 machine. Under Windows Server 2000 I have no problems.

Any help would be greatly appreciated.

Thanks
Jaime
