In this topic we will discuss about various tools that can
be used to diagnose and trouble shoot network connectivity.
-
Event Viewer
-
Windows Network Diagnostics
-
IPConfig
-
Ping
-
Tracert
-
Nslookup
-
Pathping
Event Viewer
-
Event viewer is one of the component of Microsoft Operating System.
-
It is available since Windows NT since its release in 1993.
-
Event viewer is centralized log service that report events that have taken
place, such as a failure to start component, services and application.
-
When any such error happens, Window records the event in
appropriate event log.
-
You can view log for Application, Security, Setup and
System log, look for errors, and diagnose it.
Windows Network Diagnostics
-
Windows Network Diagnostics can be used to diagnose and
correct networking problems.
-
When network problem happens, executing Windows Network
Diagnostics will show you possible description of problem and possible
solutions.
-
However some solutions might need manual interaction to
resolve problems.
IPConfig
-
Stands for Internet Protocol Configuration.
-
This command display current TCP/IP configuration for
IPv4, IPv6, DHCP and other details.
-
It can be used to review and renew IP details, and flush
DNS resolver cache.
Ping
-
This is very useful command, used to check connectivity of
current computer to another TCP/IP device.
-
Ping sends and receives ICMP (Internet Control Message
Protocol) Echo request message and display statistics in terms of bytes sent,
time taken and so on.
-
Keep in mind that Firewall or Virus Scanner might block
ICMP request.
Tracert
-
This stands for Trace Route.
-
Tracert determines the path route to destination by
sending ICMP echo request.
-
It will display list of router interfaces between Source
and Destination.
-
It will also display which router failed, what is speed or
latency.
Pathping
-
This is similar to Tracert.
-
It is a tool that combines feature of Ping and Tracert
with additional details.
-
It sends packets to each router on the way to a final
destination over given period of times.
-
Then it calculates results based on packets received from
each hop.
-
It then shows the degree of packet loss at given router or
link.
-
This can help to pinpoint which router or link is causing
network problem.
-
For example pathping -n demopc1
Nslookup
-
Nslookup is network tool that is used to obtain
information about internet server.
-
You can use it to confirm connection to DNS server and
verify that the required records exist.
