Your network contains an Active Directory domain named contoso.com. All servers run Windows Server 2012.

If you have active connection security rules, it is also helpful for troubleshooting purposes to exempt ICMP from the IPsec requirements temporarily. To do this, in the Windows Firewall with Advanced Security snap-in, in the Properties dialog box, click the IPsec Settings tab and click Yes to Exempt ICMP from IPsec.
