How can I remove or restrict the Network directory in windows explorer?

Hi Everyone,

I just need a little help on how can I remover or restrict the “Network” directory under windows explorer. see image location below:

Start -> Computer -> (Left pane) Network —> where it display all computers connected on the network.

Objective: I don’t want anybody see the lists of computers in the network by directly clicking the “Network” icon.

Thanks,
Jessie
