What you want is already the default behavior. Did you change the defaults?
What I am talking about: by default, network discovery is disabled and the firewall is on - network neighborhood will be empty when populated with win7 computers on default settings.

yes by default it is disabled but I have enabled it . what to be done now ? as  some of the folders in same network are shared and my users are using them
McKnifeCommented:
For share access, you don't need network discovery, nor you need file and printer sharing.
Only the computer hosting the share needs the file and printer sharing services. So disable both on all clients and all is as you want it.

how should I disable network discovery , please guide through
McKnifeCommented:
You mean, you turned it on but you don't remember where you did that? Because it can be turned off at the same spot.
open network and sharing center and turn it off: Control Panel\All Control Panel Items\Network and Sharing Center\Advanced sharing settings ->network discovery

If you need to deploy this via policy, use a start script for your domain:
netsh advfirewall firewall set rule group="network discovery" new enable=no

There's a difference in not showing the network list of computer, and correctly setting up all the access rights. Hiding it when having wrong access rights is useless, they'll still be able to connect to it (even if the user doesn't know, malware will be able to use it). Showing the list, but having the correct access rights doesn't really matter, as the correct access rights will not allow them to connect to those computers anyway (so malware also doesn't have access).
