You need to be logged in to your machine as a local user e.g.
Administrator for this to work.

1) Create a local user and add him to Administrators and ORA_DBA groups
or if using Administrator then add Administrator to ORA_DBA group.
2) Put sqlnet.authentication_services = (NTS) in your sqlnet.ora file.

Try again.
