All,

when trying to connect to Oracle 8i DB on WIN NT we get the following error:

ORA-24327 need explicit attach before authenticating a user


When looking on the Oracle Information CD I find the following explanation:

Cause: A server context must be initialized before creating a session.

Action: Create and initialize a server handle.

We checked the SQLNET.ORA, the TNSNAMES.ORA, which we even copied from another PC which is able to connect. I called Oracle Support, but unfortunatly, they weren't very usefull.
Does anyone have a solution for this?

THX?

Rik
