DESCRIPTION

The Remove-WSManInstance cmdlet deletes an instance of a management resource that is specified in the ResourceURI

and SelectorSet parameters. This cmdlet uses the WinRM connection/transport layer to delete the management resource instance.

PARAMETERS

-ApplicationName

Specifies the application name in the connection. The default value of the ApplicationName parameter is WSMAN.

The complete identifier for the remote endpoint is in the following format:

://:/

For example: `http://server01:8080/WSMAN` Internet Information Services (IIS), which hosts the session, forwards requests with this endpoint to the specified application. This default setting of WSMAN is appropriate for most uses. This parameter is designed to be used if many computers establish remote connections to one computer that is running Windows PowerShell.

In this case, IIS hosts Web Services for Management (WS-Management) for efficiency.

Required? false Position? named Default value None Accept pipeline input? False Accept wildcard characters? false

-Authentication

Specifies the authentication mechanism to be used at the server. The acceptable values for this parameter are:

- Basic. Basic is a scheme in which the user name and password are sent in clear text to the server or proxy.

- Default. Use the authentication method implemented by the WS-Management protocol. This is the default. -

Digest. Digest is a challenge-response scheme that uses a server-specified data string for the challenge. -

Kerberos. The client computer and the server mutually authenticate by using Kerberos certificates. -

Negotiate. Negotiate is a challenge-response scheme that negotiates with the server or proxy to determine the

scheme to use for authentication. For example, this parameter value allows for negotiation to determine

whether the Kerberos protocol or NTLM is used. - CredSSP. Use Credential Security Support Provider (CredSSP)

authentication, which lets the user delegate credentials. This option is designed for commands that run on one remote computer but collect data from or run additional commands on other remote computers. Caution: CredSSP delegates the user credentials from the local computer to a remote computer. This practice increases the security risk of the remote operation. If the remote computer is compromised, when credentials are passed to it, the credentials can be used to control the network session. Required? false Position? named Default value None Accept pipeline input? False Accept wildcard characters? false

-CertificateThumbprint

Specifies the digital public key certificate (X509) of a user account that has permission to perform this action. Enter the certificate thumbprint of the certificate.

Certificates are used in client certificate-based authentication. They can be mapped only to local user

accounts; they do not work with domain accounts.

To get a certificate thumbprint, use the Get-Item or Get-ChildItem command in the Windows PowerShell Cert:

drive. Required? false Position? named Default value None Accept pipeline input? False Accept wildcard characters? false

-ComputerName

Specifies the computer against which to run the management operation. The value can be a fully qualified domain name, a NetBIOS name, or an IP address. Use the local computer name, use localhost, or use a dot (.) to specify the local computer. The local computer is the default. When the remote computer is in a different domain from the user, you must use a fully qualified domain name must be used. You can pipe a value for this parameter to the cmdlet. Required? false Position? named Default value None Accept pipeline input? False Accept wildcard characters? false

-ConnectionURI

Specifies the connection endpoint. The format of this string is as follows:

://:/

The following string is a correctly formatted value for this parameter: `http://Server01:8080/WSMAN` The URI must be fully qualified. Required? false Position? named Default value None Accept pipeline input? False Accept wildcard characters? false

-Credential

Specifies a user account that has permission to perform this action. The default is the current user. Type a user name, such as User01, Domain01\User01, or User@Domain.com. Or, enter a PSCredential object, such as one

returned by the Get-Credential cmdlet. When you type a user name, this cmdlet prompts you for a password.

Required? false Position? named Default value None

Accept pipeline input? True (ByPropertyName)

Accept wildcard characters? false

-OptionSet

Specifies a set of switches to a service to modify or refine the nature of the request. These resemble

switches used in command-line shells because they are service specific. Any number of options can be specified.

The following example demonstrates the syntax that passes the values 1, 2, and 3 for the a, b, and c parameters:

`-OptionSet @{a=1;b=2;c=3}`

Required? false Position? named Default value None Accept pipeline input? False Accept wildcard characters? false

-Port

Specifies the port to use when the client connects to the WinRM service. When the transport is HTTP, the default port is 80. When the transport is HTTPS, the default port is 443.

When you use HTTPS as the transport, the value of the ComputerName parameter must match the server's

certificate common name (CN). However, if the SkipCNCheck parameter is specified as part of the SessionOption parameter, the certificate common name of the server does not have to match the host name of the server. The SkipCNCheck parameter should be used only for trusted computers. Required? false Position? named Default value None Accept pipeline input? False Accept wildcard characters? false

-ResourceURI

Specifies the URI of the resource class or instance. The URI is used to identify a specific type of resource, such as disks or processes, on a computer. A URI consists of a prefix and a path of a resource. For example: `http://schemas.microsoft.com/wbem/wsman/1/wmi/root/cimv2/Win32_LogicalDisk`

`http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/CIM_NumericSensor`

Required? true Position? 0 Default value None Accept pipeline input? False Accept wildcard characters? false

-SelectorSet

Specifies a set of value pairs that are used to select particular management resource instances. The SelectorSet parameter is used when more than one instance of the resource exists. The value of SelectorSet must be a hash table. The following example shows how to enter a value for this parameter:

`-SelectorSet @{Name="WinRM";ID="yyy"}`

Required? true Position? 1 Default value None

Accept pipeline input? True (ByPropertyName, ByValue)

Accept wildcard characters? false

-SessionOption

Specifies extended options for the WS-Management session. Enter a SessionOption object that you create by

using the New-WSManSessionOption cmdlet. For more information about the options that are available, type

`Get-Help New-WSManSessionOption`.

Required? false Position? named Default value None Accept pipeline input? False Accept wildcard characters? false

-UseSSL []

Specifies that the Secure Sockets Layer (SSL) protocol is used to establish a connection to the remote computer. By default, SSL is not used.

WS-Management encrypts all the Windows PowerShell content that is transmitted over the network. The UseSSL

parameter lets you specify the additional protection of HTTPS instead of HTTP. If SSL is not available on the port that is used for the connection, and you specify this parameter, the command fails. Required? false Position? named Default value False Accept pipeline input? False Accept wildcard characters? false This cmdlet supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, WarningAction, WarningVariable, OutBuffer, PipelineVariable, and OutVariable. For more information, see about_CommonParameters (https:/go.microsoft.com/fwlink/?LinkID=113216).

INPUTS

None This cmdlet does not accept any input.

OUTPUTS

None This cmdlet does not generate any output.

NOTES

The Remove-WmiObject cmdlet, a Windows Management Instrumentation (WMI) cmdlet, is similar. Remove-WmiObject *

uses the DCOM connection/transport layer to create or update WMI instances.

Example 1: Delete a listener

PS C:\>Remove-WSManInstance -ResourceUri winrm/config/Listener -SelectorSet

Address=test.fabrikam.com;Transport=http

This command deletes the WS-Management HTTP listener on a computer.
