What are the different default and optional access control models for
the following systems:

Win NT

Win 2000 (workstation and server)

Win XP

Win 2003 Server

I read multiple reports that differ in opinion.  Some say DAC for NT
and 2000 and others say MAC and then some others say RBAC.

I think that an upgrade exists to enable RBAC in NT and 2000 but that
default it is DAC.

Did Microsoft first introduce RBAC in Windows XP and 2003?
