Two possible options I know of - if you do not need to logon using your Network Credentials then rmove the Line

SQLNET.AUTHENTICATION_SERVICES= (NTS)

from the SQLNET.ORA file.

Another possibility is to open the properties of your Network Connection and go to the Authentication Tab - disable the Option

Enable 801.x Authentication on this network

OR

change the dropdown to something other than Smart Card and Certificates.

This setting can sometimes conflict with the Kerberos DLL and cause the NT Authentication from Oracle to fail. A more knowledeable person might be able to give you the reasons why this happens but between Windows Patches and the Complexities of Kerberos Token Passing - I did not have the 18 months to get down to that level.

IMPORTANT NOTE - CHECK WITH YOUR SYSTEM ADMINISTRATOR BEFORE TRYING EITHER OF THESE SUGGESTIONS.
