WMI missing security settings



http://msdn2.microsoft.com/en-us/library/aa375062.aspx

This page says that we should be able to retrieve eight settings using WMI:
ClearTextPassword
PasswordComplexity
RequireLogonToChangePassword
ForceLogoffWhenHourExpire
LSAAnonymousNameLookup
EnableAdminAccount
EnableGuestAccount
TicketValidateClient

Howerver, we are only able to retrieve four of them:
ClearTextPassword
PasswordComplexity
RequireLogonToChangePassword
ForceLogoffWhenHourExpire

Any idea why the other four are missing?

Thanks
