Good Evening:

I read about the User Authentication in W2K Professional/Server edition on the MS KB. The article describes when a user type the user-name and password,

GINA component collects the user-name/password.
GINA passes it Local Security Authority for Authentication.
LSA passes the user-name/password to Security Support Provider Interface(SSPI). SSPI, is an interface that communicates to both Kerberos and NTLM services.
For Local authentication, SSPI passes the user-name/password to NTLM Driver MSV1-0 SSP. The NTLM drivers uses NetLogon service to authenticate the user against the local SAM database.

Now, I understand the process. But what good is the information, if I don't know how to use it. Could someone guide me or provide any ideas how I can explore this information further to enhance my knowledge.

Thankyou & Your Thoughts Are Greatly Appreciated.
