Hi ED,

I am going to download your class, and try to use the API you indicated.
Actually, I will try to login with a specific userid/password, becouse that's what I want.
I will try to log in the NT server with a user/password that only the aplicattion "knows". None will be allowed to login in this server by other way.
It's some kind of security policie.

Thanks for your help, if I have any problem I will ask for some adicional help.

Carlos Oliveira.
