[Samba] [smb.conf] "hosts allow" → "Network Error. Windows cannot access \\SERVER"

[Gilles]

Hello

For some reason, restricting use by adding "host name" prevents even the 
authorized host from accesssing Samba. Access is recovered by commenting 
that line and restarting smbd. What's wrong with that line?

Thank you.
