In this post, I’1000 going to show yous the best Windows cmd commands that every network and system administrator should know.
I still prefer these bones windows commands over PowerShell for bones troubleshooting tasks. The good matter is these commands are uniform with PowerShell so yous tin use them from the Windows control prompt or PowerShell console.

- net stop and net start
- telnet client
What are Windows CMD Commands?
Windows commands are small-scale programs that collaborate with the operating organization to provide you with systems information. They are likewise used to automate many It operations that administrators must perform. PowerShell is the predecessor to the Windows command prompt just it notwithstanding remains function of the Windows operating system. All windows commands can exist run from the PowerShell console and used in scripts.
Although PowerShell is the preferred choice for automating operations there are still many cracking Windows commands that yous should know. They are yet the best option for bones network and estimator troubleshooting. In add-on, they are dandy for getting systems details like the IP address, hostname, and then on.
When an Information technology technician works on a estimator they will often use windows commands to get arrangement details and troubleshoot an issue. In this guide, I walk through many of those commands used by the helpdesk and sysadmins.
The ping control tests network connectivity between two devices by sending ICMP echo requests. For example, computer A tests if information technology has connectivity to reckoner B past sending some packets back and forth.
The ping command is still one of my favorite tools for testing basic network connectivity. It’southward fast and very easy to use. In addition, I use it for the following:
- Exam for bundle loss
- Test latency
- Examination DNS queries
- Examination connectivity with configuring new connections (can my router talk to the next hop such every bit the ISPs router?)
To exam the connectivity to some other device by IP or hostname utilize the command beneath
or by hostname
For most windows commands you can type the command followed by /? to view the help info, information technology will brandish the full syntax and parameters. So to view the assistance for ping utilize this command:
More Ping Examples
-l switch specifies a package size
ping -l 2024 192.168.five.1
-a switch will do a reverse name resolution on the IP (PTR record lookup)
ping -a 126.96.36.199
-t switch will exercise a continuous ping. A very popular command for testing network connectivity.
ping -a 192.168.5.1
Send any command output to a text file
ping -t > c:\it\examination-ping.txt
Here is the ping command ran from PowerShell. It’s the exact same syntax as using CMD.
For more details on the ping command see Microsoft’s ping documentation.
ipconfig is used to display organisation TCP/IP configuration. You tin can display the IP info for a unmarried or all network cards installed on a computer.
Only.. Look in that location is more than!
This control tin can too display the DNS cache on the local machine, affluent DNS, release and renew the DHCP address on all network cards.
ipconfig command example
To view the IP configuration for all network cards on a estimator type the command beneath and press enter
Here are some additional parameters that I find useful. Remember yous can type ipconfig /? to view the unabridged command syntax and list of parameters.
More ipconfig examples

/renew switch will renew DHCP address for all network cards
/displaydns switch volition brandish the DNS client enshroud.
The nslookup command is used to check DNS records and troubleshoot DNS. This is a must-have command for any sysadmin or network engineer. Yous can practise all kinds of tests to verify DNS is working correctly, yous can check PTR, A, MX, SOA, and many other types of DNS records. It’s another one of my favorite windows commands for network troubleshooting.

The tracert command is used to rail the pathway a packet takes from a source IP to the destination address. This simply ways it’due south going to display each hop (router) that the package passes through to reach its destination.
This control I don’t use very frequently only still comes in handy when troubleshooting the network. For example, we had some speed problems with a website from our Internet service provider, on a different ISP we had no bug. The Internet service provider had united states run a traceroute so they could run into the path information technology took.
The syntax for this command is tracert followed by the hostname or IP.
This control has very few options. The only command line switch on this one that I find useful is the -d which is used to not resolve the address to hostname.
The shutdown command does exactly that, it shuts down a computer. This control is useful for shutting down or restarting local or remote computers. It likewise provides a quick mode to see all the logs for why a computer restarted or was shut down.
This control volition restart reckoner pc2
shutdown /r /yard \\pc2
This command volition close downwardly the remote computer
shutdown /due south /m \\pc2
View previous shutdown/restart logs
Here is an case output for the shutdown /d command. This can be useful to speedily check why a computer restarted or shutdown.
More shutdown examples
Some of these utilise multiple switches, refer to the assist file shutdown /? for an explanation of each command switch.
Log user off of a remote reckoner

Shutdown local estimator and specify fourth dimension period before shutdown in seconds
shutdown /south /t 60
Shutdown a remote computer with a custom message
shutdown /m \\pc2 /c "Rebooting computer, have a squeamish day"
Abort a system shutdown
Forcefulness applications to close without warning
shutdown /s /f
The gpupdate command is used to apply group policies on a reckoner in a windows domain. This is a very popular command, I see a lot of helpdesk techs that employ it. Sometimes you lot can run this command to refresh the GPOs and avoid a reboot but that doesn’t ever work.
gpupdate command examples
This control will pull downward whatsoever GPO changes to the calculator
Utilize this choice to reapply all the GPOs on the computer.
This is such an awesome command.
The netstat command displays TCP/IP connexion data, ethernet stats, and the computer’s routing tabular array. Every bit a sysadmin I apply this command on Windows servers and clients when troubleshooting connexion issues. I tin verify application servers are working correctly by checking that the service is running and listening for connections on the port.
netstat command examples
Display all active and listening ports
Display all connections in numerical order
netstat -a -n
Here is the output of the higher up command. You tin can see how y’all can verify server and client connectivity. It shows that my domain controller with IP 192.168.100.x has established these four connections with IP 192.168.100.11.

That is it for this command, there are no boosted parameters.
The systeminfo command displays configuration details on a computer such every bit OS proper noun and version, hardware data, boot time, logon server, and more than.
There are a lot of details this command displays, I typically use it to bank check final boot fourth dimension, logon server, and Bone version.
Y’all tin run this command on remote computers with the /south parameter
system info /southward pc1
This command returns the MAC accost from all the network cards on a organization. When troubleshooting a customer connection issue I volition often demand the computer’s MAC address so I tin can verify I see information technology continued on the switch. This command is the best way to quickly catch a computer’s MAC address.
To run it on a local computer merely type getmac.
To run on a remote computer use the /s parameter
getmac /s pc1
The gpresult command reports on what grouping policies and settings are applied to a user or reckoner.
This is some other must know command if you work with Agile Directory servers.
To display all practical GPOs run this command. Note: You need to run the command prompt in administrator mode or it will non generate a total report.
The above command volition requite a report for both user and figurer applied GPOs.

I apply the windows telnet client to test if a remote host is allowing connection on a specific port. I typically utilize this when someone says your firewall is blocking a program from working.
If you know the port number the application runs on you lot tin can use the control below. In this instance, I installed filezilla server so port 21 should exist open.
The syntax is telnet + hostname or IP + port number
telnet srv01 21
You lot may or may not go a response back from the remote server. In this case with filezilla I do. You lot could as well simply get a blank screen on a successful connection.
If it doesn’t get a connexion you should get a message like the below.
That is all I utilize the telnet customer for. For complete command syntax view Microsoft’s telnet documentation.
15. gear up
