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
