Oh - I wholeheartedly agree. I was just making the point about Netware
because a poster on this thread was comparing the performance of his
Netware server to Samba with oplocks disabled.  If your clients are
using SMB, obviously the server must speak SMB! ;-)

My Netware experience predates NCP over TCP/IP. I shutdown my last
Netware 3.11 server in 1994 to replace it with Samba on Linux!  That
server was a bear to get up too - it was on a PS/2 Model 80
(Microchannel anyone?), and I had to roll my own ethernet driver for
Linux to work with the Microchannel ethernet card I had available.  That
took about 2 weeks of kernel hacking at the time.... but ultimately, the
Samba on Linux solution scaled much better than Netware did on that
386-20 system.....
