Oh, sorry, i thought that you only sent the "share" part :-[ .
My smb.conf have this:
### Optimizaciones
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536
strict sync = no
sync always = no
#Logs
log level = 1
syslog = 0
log file = /var/log/samba/%m
max log size = 50
Maybe it help, it have some optimizations and avoid syslog. I'm using a
lot of W7 PCs connected without problem with that options in a Samba 3.6.6.
