PING
Ping is used to determine if a connection exists between
your computer, and another computer connected via TCP/IP. It sends small
packets of information to the other computer, which are returned if the
connection is found, and lost otherwise. Ping is a powerful utility to help
determine network related problems.

TRACERT
The tracert command is very similar to ping, and is used to
visually see a network packet being sent and received and the amount of hops
required for that packet to get to its destination. It shows you exactly how
far a packet can go before it fails. This will help you know if the connection
problem is close, or more towards the destination.
SYNTAX
tracert [-d] [-h maximum_hops] [-j host-list] [-w timeout] target_name
SYNTAX
tracert [-d] [-h maximum_hops] [-j host-list] [-w timeout] target_name
- -d - Do not resolve addresses to hostnames.
- -h - maximum_hops Maximum number of hops to search for target.
- -j - host-list Loose source route along host-list.
- -w - timeout Wait timeout milliseconds for each reply.
EXAMPLES
The following is an example when we
used tracert on helpdesk.doit.wisc.edu. As you can see in the below example we
had a very short list / time to get to its destination because we are so close
to the web server.
C:\>tracert helpdesk.doit.wisc.edu
Tracing route to helpdesk.doit.wisc.edu [144.92.9.69]
over a maximum of 30 hops:
1 2
Trace complete.
Here is another tracert to Google.com, a much further destination.
C:\>tracert www.google.com
Tracing route to google.lb.google.com [216.239.37.100]
