Hi everybody,
When using Samba as a PDC, does it means your Domain work as a W2K domain,
NT4 domain or workgroup ? ?

This is important because when you have a W2K stand-alone server using
Terminal Server, the Terminal Server Licensing service doestn't function on
a server that is not Domain Controller (case W2K domain), and function on
any server (case NT domain or workgroup).

So you have an idea ? ?
Thanks for all
Gilles
