There’s no “advertising” of the service
There must be, in some form or other, or Windows machines wouldn’t be able to browse for it. They’d have to port-scan every IP address on the LAN.
I suspect he meant that there's no advertising of the specific service, but as a proxy he's browsing for "all Windows computers" without realizing that he is in fact browsing for other advertised services, because there is no browsing without advertising.
Doesn't Windows use LLMNR for this kind of advertising, similar to how OSX uses Bonjour. That uses multicast address 224.0.0.252, port 5355, ipv6: FF02:0:0:0:0:0:1:3. Fire up wireshark and have a sniff on your network, should be able to see something. If that's what it's using, all you have to do is implement RFC4795 (http://tools.ietf.org/html/rfc4795) :)
