Yeah, I know. Unfortunately, it was not possible for me to write a more specific error message due to there being a lot of reasons for the error.

Anyway, it sounds like Oracle is trying to authenticate you using Windows authentication and it is failing. To get around this, go into sqlnet.ora and change:

SQLNET.AUTHENTICATION_SERVICES=(<current value>)

to:

SQLNET.AUTHENTICATION_SERVICES=(BEQ, NONE) That will tell Oracle to use your password for authentication.

I don't know why you are getting this error. It may be because the installation failed.
