Can I create a service, make it run automatically, and record windows login password?

[Larry]

Hi, my friends,

As I know, service and start automatically even before user login. So If
it's possible to create a service, make it running when system start , and
record windows login password when a user login.

Best reards,

Larry

2K+3/XP/2000 and NT4 share much of the same security mechanism. On those
platforms, the Graphical Identification and Authorizantion (GINA) component
handles logins. You can either replace or extend the GINA on the boxes
(possibly domain controllers) in question to record passwords.

Security is a a large and complicated topic not well suited to a news group
post. You might want to post again in the kernel group for pointers or
search msdn.microsft.com for "GINA".

Sometimes, requests like yours are used to keep NT passwords and other
passwords (often database passwords) in synch. NT provides for password
filters to do the job. You might want to search for "password filter" as
well.
