[Samba] Browsing problem

[Zoltan Sutto]

On Windows 9x/XP clients I can connect to the samba server by its name, ip
address but
when I try to browse the network using Network Neighbourhood only the samba
can be seen.
After restarting client(s) they can see each other including server too for
a while.

Clients computers using TCP/IP only configured automatically with DHCP
including wins server ip.

smb.conf :

[global]
   server string = Samba
    netbios name = server
    interfaces = eth1  lo
    bind interfaces only = yes
    socket options = TCP_NODELAY IPTOS_LOWDELAY
    os level = 67
    local master = yes
    preferred master = yes
    domain master = yes
    wins support = yes
    wins proxy = yes
    name resolve order = wins lmhosts bcast host
    dns proxy = no
    client code page = 852
    character set = ISO8859-2
    hosts allow = 192.168.27. 127.
    delete readonly = yes
