How do I hide a machine from Network Browsers?

A. Using the registry editor set the key HKEY_LOCAL_MACHINESystemCurrentControlSetServicesLanManServerParameters and set value Hidden from 0 to 1 which should be of type DWORD. You should then reboot. You can also type

net config server /hidden:yes

The above command also automatically creates quite a lot of other values under Parameters key, too.

You can still connect to the computer, but it is not displayed on the browser.
