Unique Windows XP Authentication

[iron33]

hi,

I need some help to do the following: i want to use a unique
authentication/logon process for Windows XP (instead of the
original Windows logon). This means that before the logon
dialog box appears i want to use my own authentication mechanism
(It uses USB drive as a hardware key, in combination with free
software tools and asymmetric cryptography with a radius server.)
If the authentication fails, /for example no USB drive/ the
original logon dialog box should appear.

Well, some of the main questions are i think:
- how can i execute my own logon application before the windows
logon dialog box appears? (maybe as a service??)
- if the logon succeed, how can i step over the original logon
dialog box and go straight to the desktop?

thx any help in advance
