Description

This cmdlet is only available on the Windows platform.

The New-CimSessionOption cmdlet creates an instance of a CIM session options object. You use a CIM session options object as input to the New-CimSession cmdlet to specify the options for a CIM session.

This cmdlet has two parameter sets, one for WsMan options and one for Distributed Component Object Model (DCOM) options. Depending on which parameters you use, the cmdlet returns either an instance of DCOM session options or returns WsMan session options.

Examples

Example 1: Create a CIM session options object for DCOM

This example creates a CIM session options object for the DCOM protocol and stores it in a variable named $so. The contents of the variable are then passed to the New-CimSession cmdlet. New-CimSession then creates a new CIM session with the remote server named Server01, using the options defined in the variable.

$so = New-CimSessionOption -Protocol DCOM
New-CimSession -ComputerName Server01 -SessionOption $so

Example 2: Create a CIM session options object for WsMan

This example creates a CIM session options object for the WsMan protocol. The object contains configuration for the authentication mode of Kerberos specified by the ProxyAuthentication parameter, the credentials specified by the ProxyCredential parameter, and specifies that the command is to skip the CA check, skip the CN check, and use SSL.

New-CimSessionOption -ProxyAuthentication Kerberos -ProxyCredential $cred -SkipCACheck -SkipCNCheck -UseSsl

Example 3: Create a CIM session options object with the culture specified

New-CimSessionOption -Culture Fr-Fr -Protocol Wsman

This example specifies the culture that is used for the CIM session. By default, the culture of the client is used when performing operations. However, the default culture can be overridden using the Culture parameter.

Parameters

-Culture

Specifies the user interface culture to use for the CIM session. Specify the value for this parameter using one of the following formats:

• A culture name in <languagecode2>-<country/regioncode2> format such as "EN-US".
• A variable that contains a CultureInfo object.
• A command that gets a CultureInfo object, such as Get-Culture

Type:	CultureInfo

Accept wildcard characters:	False

-Impersonation

Creates a DCOM session to Windows Management Instrumentation (WMI) using impersonation.

Valid values for this parameter are:

• Default: DCOM can choose the impersonation level using its normal security negotiation algorithm.
• None: The client is anonymous to the server. The server process can impersonate the client, but the impersonation token does not contain any information and cannot be used.
• Identify: Allows objects to query the credentials of the caller.
• Impersonate: Allows objects to use the credentials of the caller.
• Delegate: Allows objects to permit other objects to use the credentials of the caller.

If Impersonation is not specified, the New-CimSession cmdlet uses the value of Impersonate.

Type:	ImpersonationType
Accepted values:	Default, None, Identify, Impersonate, Delegate
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-MaxEnvelopeSizeKB

Specifies the size limit of WsMan XML messages for either direction.

Type:	UInt32

Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-NoEncryption

Specifies that data encryption is turned off.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-PacketIntegrity

Specifies that the DCOM session created to WMI uses the Component Object Model (COM) PacketIntegrity functionality. By default, all CIM sessions created using DCOM have the PacketIntegrity parameter set to True.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-PacketPrivacy

Creates a DCOM session to WMI using the COM PacketPrivacy. By default, all CIM sessions created using DCOM have the PacketPrivacy parameter set to true.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	False
Accept wildcard characters:	False

-Protocol

Specifies the protocol to use. The acceptable values for this parameter are: DCOM, Default, or Wsman.

Type:	ProtocolType
Accepted values:	Dcom, Default, Wsman
Position:	1
Default value:	None
Required:	True
Accept pipeline input:	True
Accept wildcard characters:	False

-ProxyAuthentication

Specifies the authentication method to use for proxy resolution. The acceptable values for this parameter are: Default, Digest, Negotiate, Basic, Kerberos, NtlmDomain, or CredSsp.

Type:	PasswordAuthenticationMechanism
Accepted values:	Default, Digest, Negotiate, Basic, Kerberos, NtlmDomain, CredSsp
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-ProxyCertificateThumbprint

Specifies the (x.509) digital public key certificate of a user account for proxy authentication. Enter the certificate thumbprint of the certificate. Certificates are used in client certificate-based authentication. They can only be mapped to local user accounts and they do not work with domain accounts.

To get a certificate thumbprint, use the Get-Item or Get-ChildItem cmdlets in the PowerShell Cert: drive.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False

-SkipRevocationCheck

Indicates that the revocation check for server certificates is skipped. Use this parameter only for trusted computers.

-UseSsl

Indicates that SSL should be used to establish a connection to the remote computer. By default, SSL is not used. WsMan encrypts all content that is transmitted over the network, even when using HTTP.

This parameter lets you specify the additional protection of HTTPS instead of HTTP. If SSL is not available on the port used for the connection and you specify this parameter, then the command fails.

It is recommended that you use this parameter only when the PacketPrivacy parameter is not specified.

Type:	SwitchParameter
Position:	Named
Default value:	None
Required:	False
Accept pipeline input:	True
Accept wildcard characters:	False
