What Would You Enter at the Command Prompt to Display the Shared Library Information for Executables

Anyone who works with Windows network configurations will sooner or later meet the Network Shell (Netsh). The term refers to an interface between users and the operating system, which enables the administration and configuration of local, and remote network settings.

The range of applications includes settings for the Windows firewall and LAN/WLAN direction every bit well every bit IP and server configuration. Moreover, networked infrastructure can also be protected from external assail. Using the control line tool, it's likewise possible to diagnose bug and deport out repairs in the network. A large advantage of Netsh is that network-related assistants tasks can be performed quickly and conveniently, and can exist automated with scripts.

Netsh commands: starting the control prompt

It's necessary to access the control line in club to use Netsh. There, you tin open the "Run" carte du jour as follows:

1. Press the key combination [Windows] + [R]
2. Enter "cmd" in the entry field (ane)
3. Click the "OK" button (2)

Opening the command line (cmd.exe) on Windows.

The command prompt will then launch. The service program will open up after you enter "netsh" and confirm with [Enter].

Windows command prompt with a Netsh command; hither USERNAME is a placeholder for the active user business relationship.

If Netsh commands and scripts aren't run or if more fundamental interventions in the network configuration are planned, you'll need to start Network Shell with administrator rights. These steps are required on Windows 10:

1. Correct-click on the Windows symbol on the left side of the job bar or press the key combination [Windows] + [X].
2. Choose the entry "Command Prompt (Admin)" in the context card that appears:

Starting command prompt with administrator rights.

Netsh includes the program file netsh.exe located in the Windows system folder (%windir%\system32). Directly opening the file streamlines the Netsh command entry process. You lot can enter the path C:\Windows\System32\netsh.exe into the accost line of Windows Explorer and press [Enter]. Y'all tin so enter Netsh commands directly away in the entry window that appears.

Launching the file is even faster by using a shortcut. Once created, a uncomplicated mouse click will exist enough to launch the control entry:

1. Right-click on the Windows desktop. Click on the menu entry "New" (ane) and then click on "Shortcut" in the side by side context menu (2):

Creating a Netsh shortcut via the Windows desktop.

1. In the shortcut banana, enter the path C:\Windows\System32\netsh.exe (ane) and click on "Next" (two):

Entering the program path for a Netsh shortcut.

1. Y'all should give the shortcut a suitable name (i); the shortcut will then be placed on the desktop after clicking "Terminate" (two):

Entering a suitable name for the Netsh shortcut.

How Netsh works

The service program Netsh provides an extensive command syntax. If y'all desire to consummate certain tasks, you'll need to familiarize yourself with the specific construction of the Network Shell. The construction of the service program is based on contexts that stand for various assistants levels. Each context encompasses a certain network functionality (e.g. IP, LAN and firewall configuration). The program uses the files of the Dynamic-Link Library (DLL) for context-spring interaction with other Windows components. For example, Netsh utilizes Dhcpmon.dll to modify and manage DHCP settings.

To use a context, it's necessary to switch to it in the command prompt of Windows. For example, the "LAN administration" context is accessed as follows:

1. After opening the command prompt, enter "netsh" and ostend with [Enter].
2. Then enter "lan" and confirm with [Enter].
3. The command prompt will now evidence the context change: netsh lan>

Netsh in the command prompt: switching levels to the "LAN" context.

After changing to the "LAN" context, a number of context-specific and cross-context commands will be available. The context-specific commands include "set" (which configures settings at interfaces). An example for a full general and cross-context Netsh command is the aid control "/?", which lists the available sub-contexts and commands in each section. Entering information technology in the "LAN" department will produce the following list of context-specific and cross-context commands:

Netsh in the command prompt: calling up the command overview for the "LAN" context.

For case, if you lot switch to the firewall context, the associated command reference will await like this:

Netsh in the command prompt: calling up the command overview for the "firewall" context.

Too the context-leap structure, there are other special points to consider when using the program. Netsh can either be used in a non-interactive or interactive mode. In the non-interactive mode, for example, of import network settings are exported to a text file and reimported for subsequent recovery.

In the interactive mode, directly requests can exist initiated. If you enter "netsh interface ip show address", the current IP accost of the computer volition be displayed. The interactive manner can be used online or offline. The online model directly implements operations, while the offline mode saves actions and runs them later. The saved actions are activated at the desired time via the Netsh command "commit".

Netsh commands and their contexts

Nosotros've summarized the principal Netsh commands with a brusk explanation of the contexts in the table below. In the instance of general, cross-context commands, boosted explanations are not necessary (right-mitt column). Depending on the operating organization version and the part in the network (client or server), the bachelor commands may vary in some instances. The control entry on a computer with a Windows Server 2016 data center is equally follows:

Command	Implementation	Netsh context managed
..	Switches to a context level higher

Syntax parameters for Netsh – what do they mean?

To implement specific actions and tasks, Netsh commands can be given optional parameters. The syntax scheme for the combination of Netsh commands and parameters is every bit follows:

            netsh [-a AliasFile] [-c Context] [-r RemoteComputer] [-u [DomainName\]UserName] [-p Countersign | *] [control | -f ScriptFile]          

The following parameters are all optional, so they can be added and used where needed.

-a	Return to Netsh command prompt afterwards running the allonym file
AliasFile	Specifies the name of the text file that contains at least one Netsh command
-c	Switches to the specified Netsh context
Context	Placeholder for the context to be entered (due east.g. WLAN)
-r	Causes the command to be run on a remote computer; the remote registration service must be executed there.
RemoteComputer	Name of the remote reckoner that is configured
-u	Indicates that the Netsh control is run under a user account
DomainName\	Designates the user business relationship domain (the standard value is the local domain if no special domain is specified)
UserName	Name of the user account
-p	A password can be entered for the user account
Password	Specifies the countersign for the user account that is stated with -u UserName
NetshCommand	Netsh command to be run
-f	Ends Netsh later on running the script file
ScriptFile	Script to be run

Resetting the TCP/IP Stack with Netsh

A common use for Netsh commands is to reset the TCP/IP stack, which provides for the commutation of data packages in networks. In the event of network and cyberspace issues, this measure tin can help to remove defective or incorrectly configured TCP/IP protocols for example. The post-obit repair command executes a reset and re-installs TCP/IPv4:

A protocol file tin can too exist created that logs the changes fabricated:

            netsh int ip reset c:\tcpipreset.txt          

After running the reset, the computer will need to be restarted.

Tip

Netsh commands can also be used in batch files (*.bat) to automate routine tasks. Discover out more in our guide "Removing Batch Files".

Importing and exporting network settings

Netsh allows you to export current network settings into a plain text file. In case of network issues, a functioning and error-free configuration tin can and then be quickly restored.

In the first step (export), the network configuration is read out, written into a text file (netcnfig.txt)), and saved in the case directory "Network Configuration" on the C:\ drive. Before the start consign, you'll demand to manually create the "Network Configuration" folder on the destination bulldoze (Netsh does not perform this step automatically). So, switch to the command prompt and enter the lawmaking below:

            netsh -c interface dump>c:\Network Configuration\netcnfig.txt          

The following command entry is required for subsequently importing the settings:

            netsh -f c:\Network Configuration\netcnfig.txt          

Tip

Windows 10 besides supports re-create and paste in the command prompt. Yous can merely copy the command syntax from this commodity and insert it into the entry window.

IP configuration with Netsh

A prevalent use case for Netsh is changing IP settings. If a computer in the network doesn't contain a static IP address but an automatically assigned one, the Dynamic Host Configuration Protocol (DHCP) is used. This communication protocol automatically assigns IP addresses to clients in a network, and other required configuration data. This process takes multiple steps:

In the first pace, the current settings and names of the bachelor network adapters are requested:

            netsh interface ipv4 show interface          

Calling up the available network adapters with Netsh.

Now a sure LAN adapter (in this case: Ethernet) is determined as the addressee for the IP assignment via DHCP.

            netsh interface ipv4 set address name="Ethernet" source=dhcp          

Next, DHCP applies the dynamic assistants for network settings that chronicle to the Ethernet adapter.

Activating and deactivating Windows firewall

If you lot wish to actuate or conciliate the Windows firewall, all y'all need is a uncomplicated Netsh control syntax. A firewall is activated as follows:

            netsh firewall prepare opmode enable                      

Firewall deactivation requires the following command:

            netsh firewall gear up opmode disable          

Notation

In some contexts, Windows will recommend alternatives to network administration with Netsh. Hither, Windows PowerShell is often suggested and you tin can find an introduction to it in our Digital Guide.
