Network numpty, can this be done???

erm, i'm not sure, but it may be a firewall problem.

temporarily disable the windows firewall on your 7 machine, and see if your kids can connect.

if so, we can help you change your firewall settings permanently.

*edit* you guessed the answer whilst i was posting. :)

Thanks again for the reply.

I managed to get it to work. I just played around with the firewall settings.

I will have a better look at it tomorrow, and retest to see if it still works.
