Great information to have. Where do set the 'OS level' in samba. I don't
have my Samba book on hand. Do I just put it in the global settings in the
smb.conf?
I want the Samba server to be my master browser. One of my next todo's is
having the Samba server emulate a domain controller. I'm going to have to
get the new Samba 3.0 material too!
Thanks,
James

The OS Level statement goes in the global section of smb.conf.
BTW, I'm still running Samba 2.2 that came with Red Hat 9 and this machine is a Windows PDC, a DNS, WINS and DHCP server, and my Windows clients have no idea it is running Linux. I seem to remember that Samba 3.0 allows you to provide full Active Directory emulation for Win2K and later clients, something that 2.2 can't do. The point I am making is that if you want to use the Samba installation that comes with Red Hat 9, Windows is OK with that. Since Windows isn't secure anyway, the version of Samba you use is not of great consequence unless you already have an Active Directory environment.
