SSPI Kerberos Window NT 4.0

[Burruss, Dante M]

I have a question, If SSPI using Kerberos protocol service installed on a
remote server (Window NT), in order for tickets from the client desktop to
be interpret by the KDC and authentification to take place the on the server
the client (desktop) must also have kerberos (client software) installed on
there computer?  If this is true, what happens if you install SSPI on remote
server and a client try's to access the server and client don't have
kerberos  installed on there system?  

I have a website where I need to authenticate using ASP and I need to get
the client public token for authentification. I need to fully understand how
to use Kerberos and install software.

Your response will greatly be appreciated.

Thanks
