I solved the problem enabling a firewall rule in the machine1 following these steps:

1. Click on Start Icon
2. Type "Windows Firewall"
3. Click on Windows Firewall with Advanced Security
4. Click on Inbound Rules 
5. Look for the following rule:
    • Name: "File and Printer Sharing (Echo Request - ICMPv4-In)"
    • Profile: "Private,Public"
6. Right Click on the rule
7. Click on "enable rule"
