Win32_NetworkClient - powershell.one

The Win32_NetworkClient WMI class represents a network client on a Windows system. Any computer system on the network with a client relationship to the system is a descendant (or member) of this class.

Methods

Win32_NetworkClient has no methods.

Properties

Win32_NetworkClient returns 6 properties:

'Caption','Description','InstallDate','Manufacturer','Name','Status'

Unless explicitly marked as writeable, all properties are read-only. Read all properties for all instances:

Get-CimInstance -ClassName Win32_NetworkClient -Property *

Most WMI classes return one or more instances.

When Get-CimInstance returns no result, then apparently no instances of class Win32_NetworkClient exist. This is normal behavior.

Either the class is not implemented on your system (may be deprecated or due to missing drivers, i.e. CIM_VideoControllerResolution), or there are simply no physical representations of this class currently available (i.e. Win32_TapeDrive).

Caption

STRING MAX 64 CHAR

A short textual description of the object.

Get-CimInstance -ClassName Win32_NetworkClient | Select-Object -Property Name, Caption

Description

STRING

A textual description of the object.

Get-CimInstance -ClassName Win32_NetworkClient | Select-Object -Property Name, Description

InstallDate

DATETIME

Indicates when the object was installed. Lack of a value does not indicate that the object is not installed.

Get-CimInstance -ClassName Win32_NetworkClient | Select-Object -Property Name, InstallDate

Manufacturer

STRING

Name of the manufacturer of the network client running on the computer system running Windows.

Example: “Microsoft Corporation”

Get-CimInstance -ClassName Win32_NetworkClient | Select-Object -Property Name, Manufacturer

Name

KEY PROPERTY STRING

Network name of the network client running on the computer system running Windows.

Example: “Microsoft Windows Network”

Get-CimInstance -ClassName Win32_NetworkClient | Select-Object -Property Name

Status

STRING MAX 10 CHAR

Current status of an object. Various operational and nonoperational statuses can be defined. Available values:

$values = 'Degraded','Error','Lost Comm','No Contact','NonRecover','OK','Pred Fail','Service','Starting','Stopping','Stressed','Unknown'

Get-CimInstance -ClassName Win32_NetworkClient | Select-Object -Property Name, Status

Selecting Properties

To select only some properties, pipe the results to Select-Object -Property a,b,c with a comma-separated list of the properties you require. Wildcards are permitted.

Get-CimInstance always returns all properties but only retrieves the ones that you specify. All other properties are empty but still present. That’s why you need to pipe the results into Select-Object if you want to limit the visible properties, i.e. for reporting.

Selecting Properties

The code below lists all available properties. Remove the ones you do not need:

$properties = 'Caption',
              'Description',
              'InstallDate',
              'Manufacturer',
              'Name',
              'Status'
Get-CimInstance -ClassName Win32_NetworkClient | Select-Object -Property $properties

Limiting Network Bandwidth

If you work remotely, it makes sense to limit network bandwidth by filtering the properties on the server side, too:

Get-CimInstance -Class Win32_NetworkClient -Property $property | 
Select-Object -Property $property

Selecting Instances

To select some instances, use Get-CimInstance and a WMI Query. The wildcard character in WMI Queries is % (and not “*”).

The parameter -Filter runs a simple query.

Listing all instances where the property Caption starts with “A”

Get-CimInstance -Class Win32_NetworkClient -Filter 'Caption LIKE "a%"' 

Using a WQL Query

The parameter -Query uses a query similar to SQL and combines the parameters -Filter and -Property. This returns all instances where the property Caption starts with “A”, and returns the properties specified:

Get-CimInstance -Query "SELECT Description, Status, InstallDate, Caption FROM Win32_NetworkClient WHERE Caption LIKE 'a%'"

Any property you did not specify is still present but empty. You might need to use Select-Object to remove all unwanted properties:
Get-CimInstance -Query "SELECT Description, Status, InstallDate, Caption FROM Win32_NetworkClient WHERE Caption LIKE 'a%'" | Select-Object -Property Description, Status, InstallDate, Caption

Accessing Remote Computers

To access remote systems, you need to have proper permissions. User the parameter -ComputerName to access one or more remote systems.

Authenticating as Current User

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with your current identity:
$result = Get-CimInstance -ClassName Win32_NetworkClient -ComputerName $list 
$result

Authenticating as Different User

Use a CIMSession object to authenticate with a new identity:

# one or more computer names or IP addresses:
$list = 'server1', 'server2'

# authenticate with a different identity:
$cred = Get-Credential -Message 'Authenticate to retrieve WMI information:'
$session = New-CimSession -ComputerName $list -Credential $cred

$result = Get-CimInstance Win32_NetworkClient -CimSession $session

# remove the session after use (if you do not plan to re-use it later)
Remove-CimSession -CimSession $session

$result

Requirements

To use Win32_NetworkClient, the following requirements apply:

PowerShell

Get-CimInstance was introduced with PowerShell Version 3.0, which in turn was introduced on clients with Windows 8 and on servers with Windows Server 2012.

If necessary, update Windows PowerShell to Windows PowerShell 5.1, or install PowerShell 7 side-by-side.

Operating System

Win32_NetworkClient was introduced on clients with WindowsÂ Vista and on servers with Windows ServerÂ 2008.

Namespace

Win32_NetworkClient lives in the Namespace Root/CIMV2. This is the default namespace. There is no need to use the -Namespace parameter in Get-CimInstance.

Implementation

Win32_NetworkClient is implemented in CIMWin32.dll and defined in CIMWin32.mof. Both files are located in the folder C:\Windows\system32\wbem:

explorer $env:windir\system32\wbem
notepad $env:windir\system32\wbem\CIMWin32.mof
