Fedora Users — Network Server displaying nothing

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?
