All Windows 2000 domains run Active Directory.  I assume you mean it's
in "natie" mode, as opposed to "mixed" mode.

Microsoft's position on Win2k licencing is that: 

"You need ... a Windows 2000 Server Client Access License (CAL) for
each client computer that is used by an authenticated user or that
uses Windows 2000 Server Services."

... and ...

"An authenticated user is one who directly or indirectly uses the
Windows 2000 Server Integrated Sign-on Service or receives credentials
from the Windows 2000 Active Directory(TM) service."

So my reading is that if you're using a Samba server in a Windows 2000
domain, you need a CAL for each PC accessing that server.
