It's quite common for a firewall to only block traffic originating from
other hosts, so it doesn't necessarily mean anything that you can access the
laptop from the desktop. The desktop can have an active firewall that
allows it to see other machines, but prevents them from seeing it. This
might not be the "windows firewall", but some other software that is
filtering incoming traffic to your desktop.
There are several utilities will probably help you to troubleshoot this. Do
a search for network scanning tool and you'll find a lot of things that can
pinpoint a filtered (firewalled) IP address on your network. Be careful
using these tools on any IP addresses that don't belong to you, because this
is often considered a violation of your ISP's EULA.
