Windows Server 2. Netsh commands you should know. Introduction. I have written a number of different Netsh articles and other authors have published their own Netsh articles. This just shows how important and innovative Netsh really is. In this article, I will cover 1. Netsh commands that every Windows admin should know. In my opinion. Netsh is so powerful and flexible; I cannot choose the “most important” Netsh commands as the importance of a command will vary from admin to admin.

What I can do is to choose the 1. I feel will either show you valuable information or will help you out when you are in trouble. Keep in mind that these commands can be scripted (as they are all command line tools) so whatever you can do with just an individual command on a single machine, you could write a script to perform that command on all machines in your network. What is Netsh? Microsoft Windows Netsh is a command line scripting utility.
With Netsh, you can view or change the network configuration of your local computer or a remote computer. You can manually run Netsh commands or you can create batch files or scripts to automate the process. Not only can you run these commands on your local computer but also on remote computers, over the network. Netsh also provides a scripting feature that allows you to run a group of commands in batch mode against a specified computer. With netsh, you can save a configuration script in a text file for archival purposes or to help you configure other computers.
Netsh is not “new” with Windows Server 2. Windows Vista. Netsh has been around for a long time.
Netsh commands are available in Windows 2. XP, and Windows Server 2. What is new are a number of options for Netsh with Windows Server 2.
Vista. Additionally, I feel that Netsh is underutilized by admins and most admins are not aware of the new Windows Server 2. Vista Netsh enhancements. It is my hope to educate Windows admins about the new netsh features and the power of netsh in this article. What is different about Windows Server 2. Windows XP? There are a number of differences even at the core command level between the Windows XP version of netsh and the Windows Server 2.
To compare these, I ran “netsh /?” in each operating system. While Windows XP has “routing” listed as a context and Windows Server 2. Win 2. 00. 8 lacks (and that is included in the Win 2. RAS context). Otherwise, Windows Server 2. Windows XP does not: dhcpdhcpclienthttpipseclannapnetiorpcwinhttp. Thus, as you can see, there are many more “context” / options available in Window Server 2. With no more delay, let’s get started with our Netsh top 1.
Netsh commands that every admin should know.#1. How to get help. Every Windows admin should know how to get guided help with netsh. This is easy – just use the “/?” command to be guided through what you are trying to do. For example, to show all netsh contexts (categories of options), just type: netsh /?
Figure 1: Results of netsh /? For example, say that I typed netsh lan /?, I would see: Figure 2: Results of netsh lan /?
From there, I can continue with the guided help by doing- netsh lan show /? And, from there, I would see that I can show interfaces with- netsh lan show interfaces. Being able to guide yourself through the many netsh commands using /? The options are “- r” for the machine, “- u” for the username, and “- p” for the password.
Here is an example: netsh - r Win. XP- 1 - u winxp- 1\administrator - p My!
Pass. 1 interface ip show config. As you can see, I supplied the remote machine name, remote username, and password which allowed me to perform this command over the network. You can perform any of the commands shown here over the network as long as the remote machine supports that command (different operating systems will use different variations of commands).#8 – Run Netsh in interactive mode or with a script. Netsh can be run either interactively (just you typing commands manually) or when using scripting. Say that you wanted to manually step through some commands on your local machine or remote machine.
You could just start by typing netsh at the command line and you would see: netsh> From there, you can enter all the netsh commands you want, or even tell netsh to connect to a remote machine with set machine. On the other hand, you could use netsh –f < scriptfile> and specify a script that netsh would use.#7 – Open a port on your firewall. With netsh, you can quickly and easily open a port on your firewall if you know the right command. Here is an example of opening port 4.
If the command was successful, you should get a response of “Ok.”#6 – Export your current network configuration to a file and import it. With netsh, exporting and importing your IP address configuration is easy – unlike in the GUI interface. To export your configuration, just do: netsh –c interface dump > test. Figure 3: Export of IP address configuration and viewing the file. Later on this machine or on a different machine, you could import this configuration with- netsh –f test. Try out the latest Netsh uses. As mentioned above, there are a lot of new features in Windows Server 2.
Here are the new categories that I see on my Windows Server 2. For example, you can configure not only your DHCP client but also your DHCP server. You can configure IPSec encryption, the network access protection (NAP) client, and many more!
As you add other roles & features to your server, you will have additional contexts available to you. For example, if you add the network policy server to Windows Server 2.
