Prevent searching network places / network neighborhood

An issue I have come across recently was one in which a client did not want employees searching the contents of shared directories, however still wanted the ability to access the shares via the run command or address bar. In order to achieve this the only method I found was to disable the network neighborhood and remove the existing shortcuts in the directory "C:\documents and settings\%user%\nethood". In order to disable the network neighborhood discovery you must edit the following registry key.


Once in the above key you will add a DWORD titled "NoNetHood" and give it a value of "1".

This will prevent the Network Neighborhood from rediscovering the shares on the network and once you have deleted any entries in the folder mentioned earlier your search assistant will not search the network shares.

Now in the right hand pane select the following:
