How to Log a User into Win2K via Kerberose or NTLM

[Guest_imported]

Hi All

I need to be able to write a funtion to allow users to pass in name, password, domain and authentication option, where authenication option can be NTLM or Kerberose. I remember finding sample code in MSDN to do this, but upon revisiting MSDN, I cannot find it anywhere.. Anybody has sample code out there?

Thanks...
