I've created a homegroup on my main pc running 7 home premium. My laptop, running 7 starter, joins the homegroup successfully, and can access shared libraries on the main pc. BUT: the main pc won't see the laptop. I get the message "no other homegroup computers are available" when I click on Homegroup. The laptop libraries are set to share; network discovery is on; the password is obviously correct as the laptop joins and views shared desktop folders ok; time is synchronised;and both pcs are set to Home Network. I'm stuck - can anybody help?
