I've assigned 500 because this is a fairly urgent question. We're using PowerBuilder 8 at the moment but can upgrade to 10 if need be. We need to connect to a SQL Server and have that connection run through NT authentication instead of using a SQL user. I tried while setting up the connection to leave the username/password blank hoping that it would then default to the NT Authentication from the user logged into the machine but it did not. I need to know step by step how to go about doing this. Thanks in advance.
