Hide Windows Server from networkbrowsing
Hi everyone,
if you ever asked yourself how to hide a windows server on the network (e.g. from network browsing), it's quite easy. Open the terminal and enter following command:
# hide server
	net config server /hidden:yes
# unhide server
	net config server /hidden:no
Note: it can take some time before the server disappears or shows up.
