Disable Network Browsing

[wipe_out at users.sourceforge.net (WipeOut)]

Hi,

I have a PC that is just for internet access, I don't want it to be able 
to access any of the windows or samba servers on the network.. I removed 
samba-client thinking this would solve the problem but the network can 
still be browsed via Nautilus..

Is there a way to disable network browsing through any of the GUI 
interfaces?

Thanks..
