Network Server displaying nothing

[Nicholas Ruddick]

I've having a problem with Network Servers not displaying anything apart 
from Windows Servers. I have smb.conf as follows

[global]
        workgroup = LGSOC
        server string = DopeFlish Box
        security = DOMAIN
        log file = /var/log/samba/%m.log
        max log size = 50
        socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
        os level = 33
        preferred master = No
        local master = No
        domain master = No
        dns proxy = No
        wins server = 192.168.0.1
        idmap uid = 16777216-33554431
        idmap gid = 16777216-33554431
                                                                                

[homes]
        comment = Home Directories
        read only = No
        browseable = No

It did a couple of times show all the servers in my network but not now. 
I have a samba server domain controller running that is master browser 
of the network and works with all the other machines in my network so I 
don't know whats wrong. I tried changing my workgroup name in gconf but 
no joy. What should I try next?
