PathPing

Perhaps the most useful tool for isolating connectivity problems from the client, PathPing (PathPing.exe) can help diagnose problems with name resolution, network connectivity, routing, and network performance. For this reason, PathPing should be one of the first tools you use to troubleshoot network problems. PathPing is a command-line tool whose syntax is similar to that of the Tracert and Ping tools.

Note Ping's usefulness has become very limited in recent years, and it is no longer an effective tool for determining the state of network services. Ping often reports that it cannot reach an available server because a firewall, such as Windows Firewall, is configured to drop Internet Control Message Protocol (ICMP) requests. If a host is still capable of responding to ICMP requests, Ping might report that the remote host is available even if critical services on the remote host have failed. To determine whether a remote host is responding, use the PortQry support tool instead of Ping.

To test connectivity to an endpoint, open a command prompt and run the following command.

pathping destination

The destination can be a host name, a computer name, or an IP address.
