Maybe I didn't make myself clear. If I wrote the programs that I want to open, I would use Windows authentication. I want to be able to open programs written by other vendors that use username/passwords. I want to have the user enter their information once and record it somewhere. Then, when they launch Windows, those applications will automatically launch with the stored username/password for that application (those username/passwords are different for each application and they are not the same as the Windows username/password).
Hope this clears it up a little more. Thanks in advance.
