My corporate environment is windows 7 with a 2008R2 domain. I'm looking for a way to hide the network icon so my users are not able to view all network PCs and Devices. The only information I've found on the web relates to registry hacks. I'm wondering if this can simply be done with a GPO? I've turned off network discovery in an attempt to prevent it, but devices and PCs are still showing up. Any help would be greatly appreciated. Thank you.
