I can't change the SQLNET.ora file -- it's locked down. There is only 1 oracle home on the client desktop. version 10.2.02

I'm stuck with those sqlnet.ora settings, so I need to make it work. Would setting SQLNET.AUTHENTICATION_SERVICES=(NTS) on the server side, and allowing guests on the server work? And I apologize for asking something that I could just try out, but I don't have easy access to the server, so I want to make sure my time on the server is focused and I'm not just trying random things...

thanks again. Received on Tue Feb 12 2008 - 11:21:10 CST
