Don’t Display Last User Name

I need to know how to put in the Registry the same command I use on NT Workstations that does not display the last user login name. I used to put “dontdisplaylastusername” in the reg on an NT machine but when I put it in the same place on a 2000 machine it does not work. Can someone tell me where and what entry to put so I can get these results. I don’t want the last user name to be displayed when you hit “control, alt, delete” to logon.

Thanks in advance.
