    You can use IPSec on the clients to only allow NBT access to the other
    machines in the department. If you unbind the service from the NIC or turn
    it off they will all loose file and print sharing. Or block the appropriate
    ports for that VLAN.

    Subject: Blocking NetBios

    Hi list,
    I have a request from one of our clients to block NetBios in thier Network
    ( No one should be able to see the shared resources of others)
    I have googled around and all what I have found is blocking it on the edge
    communication equipment ( router, xDSL modemd..etc) Which will be done.
    The most important thing is to disable it internally ( inside the LAN)
    Any suggestions???
    Taking in consideration that there is DHCP server for the clients ( If it
    can contribute in the Solution)
    Best Regards,
    Kareem Mahgoub
