I want to fix this because it seems the reason why I cannot share ubuntu folders with my Windows machine.

Windows 7 machine network configuration:

IP: 192.168.2.2
Subnet Mask: 255.255.255.0
Gateway: 192.168.2.1
dns: 8.8.8.8, 4.4.4.4

Ubuntu machine network configuration:

IP: 192.168.2.3
Subnet Mask: 255.255.255.0
Gateway: 192.168.2.1
dns: 8.8.8.8, 4.4.4.4

I can ping my Windows machine from Ubuntu but I cannot ping my Ubuntu machine from Windows.

Any suggestions?

Maybe your iptables (aka Firewall) has rule for blocking ping requests.
You can check it easily by disabling the iptables with the command sudo ufw disable. Run the ping test again.
Enable it again with sudo ufw enable.

4.4.4.4 is not a Google DNS, Google now has established public DNS servers at 8.8.8.8, and 8.8.4.4 can additionally be used.
