I installed the cvs 2.2 samba version in a server with 100 clients (w2k
and win95) the lock problem has been solved! Thank you!
But I've a new problem: Samba is Slow compared with novell and w2k with
the same hardware.
I'll send a mail with details and numbers.
The lock problem is solved for me at least!
Thank you
Pablo
