I`m using Samba-2.2.7a on red hat 9.0 with kernel 2.4.20-18.9

        encrypt passwords = yes
        guest account = smbguest
        log level = 2

        security = user
  socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=8192 SO_SNDBUF=8192

I already made the changes on regedit in my WinXP box.

gino:x:500:500::/home/gino:/bin/bash
R32$:x:1200:300:workstation:/dev/null:/bin/false

gino:x:500:
