It's hard to say without more information, but it's quite likely that
a firewall on the Windows machine is blocking the incoming connection
necessary to initiate the conversation.

This is an incoming TCP connection, by default on port 5298, but you
can override the port in the Advanced settings of your Bonjour account
in Pidgin (note that if you change the port, some clients will be
unable to connect, so it's best to leave it as 5298).

You'll want to make sure that your firewall isn't blocking that port,
and that the remote machines can connect to your machine on that port.

If you still have issues, you'll need to get a Debug Log (Help->Debug Window).
