If a client cannot connect to a server, use PathPing to isolate which network note is causing the problem. TraceRt is similar but PathPing also provides packet loss percentages. PathPing displays a path to a TCP/IP host and reports packet losses at each router along the way.

Usage: pathping [-g host-list] [-h maximum_hops] [-i address] [-n]
[-p period] [-q num_queries] [-w timeout] [-P] [-R] [-T]
[-4] [-6] target_name

Options:
-g host-list Loose source route along host-list.
-h maximum_hops Maximum number of hops to search for target.
-i address Use the specified source address.
-n Do not resolve addresses to hostnames.
-p period Wait period milliseconds between pings.
-q num_queries Number of queries per hop.
-w timeout Wait timeout milliseconds for each reply.
-P Test for RSVP PATH connectivity.
-R Test if each hop is RSVP aware.
-T Test connectivity to each hop with Layer-2 priority tags.
-4 Force using IPv4.
-6 Force using IPv6.
