hi, i have a problem with this oracle error code. after much searching, i realised that i need to set this "sqlnet.authentication_services=(NTS)" in my sqlnet.ora. Before, i came to this , it was commented out. My services are run by local system account and hence its a user administrator.
My guess was that this parameter is used by oracle to authenticate between oracle level and the os. Hence, when this was commented, i had this error code.
So the early situation is that this line was commented in my sqlnet.ora. But i am logged in as administrator , and this supposed to have all the rights. However, i got this particular error code. Listener service was started and everything was fine.
