Netbios Broadcast from all XP machines - Windows Server

Hello, I work for a company that has just setup a new 2003 Server Network SBS 2003 with all PC's running XP. The current IT person there has been concerned about the logs on the firewall as they appear to show all PC's broadcasting themselves on the 'Internet' as they have file and print shareing enabled. If this is the case is the only way to stop this to disable file and print shareing and netbios on every machine? Thanks in advance M...

    Default Netbios Broadcast from all XP machines

    NetBIOS broadcasts cannot cross routers. So, unless the XP machines have
    public IP addresses, they cannot make such broadcasts on the Internet. What
    the firewall logs might be showing is DNS traffic if the clients are not
    properly configured to use the SBS DNS server.
