About the SQL Logins and users for the application, we did that long time ago...
Today, I want try the NT authentification...I try to find the best way to created an application in VB6 using SQL 7.0 without anyone can access by Access ODBC or another third party...

What is the advantages to use NT authentification login in SQL 7.0 ???
or
Is it secur to use NT authenfication ??? Because, if I have Login defined like a Nt group and this login is associated to a role...Everybody can access directly to my tables using access...I know it's logical...
