In-Depth Information
Ping:
Performs a basic connectivity check with a remote host.
Tracert:
Performs a more detailed connectivity check. Rather than simply reporting
whether the remote host is reachable or not, tracert will display the path taken by the
packets en route to the destination host and report the exact point along the path where
any failure is occurring.
Pathping:
This utility is available for Windows 2000 and later, and combines the best
aspects of ping and tracert. Pathping will first perform a tracert to the remote host, and
will then send a series of pings to each hop in the route to give you a detailed view of
network performance along the entire link between two hosts.
Netsh:
This is a command-line tool built into the Windows operating system that allows
you to configure a number of different aspects of TCP/IP networking, including the
Windows Firewall, basic TCP/IP configurations, DNS, DHCP, and more.
Netdiag:
Available as part of the Windows Support Tools, netdiag can perform a number
of tests to diagnose DNS, WINS, and other TCP/IP services on your network. You can
configure netdiag to run the entire battery of tests, or to only run one or two tests to zero
in on a particular troubleshooting area.
Repadmin:
If you are an Active Directory administrator, this will be a tool that you turn
to again and again. Like netdiag, it contains any number of subcommands that will allow
you to troubleshoot and report on all aspects of your AD replication topology.
Portqry:
This tool is freely downloadable from the Microsoft website and provides a way
to enumerate open ports on a local or remote computer.
Ipconfig:
This tool provides a detailed description of your computer's IP configuration
and allows you to release or renew a DHCP-assigned IP address as well as display or
flush your DNS cache.
Route:
This tool allows you to view and modify the contents of your local routing table,
which controls how remote traffic is directed on your Windows Server 2003 computer.
