DESCRIPTION

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

PS C:\> $so = New-CimSessionOption -Protocol DCOM
PS C:\> New-CimSession -ComputerName Server01 -SessionOption $so

This set of commands 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.

Example 2: Create a CIM session options object for WsMan

PS C:\> New-CimSessionOption -ProxyAuthentication Kerberos -ProxyCredential $cred -SkipCACheck -SkipCNCheck -UseSsl

This command 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.

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

PS C:\> New-CimSessionOption -Culture Fr-Fr -Protocol Wsman

This command 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:

  • Enter 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.

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 cmdlet in the Windows PowerShell Cert: drive. For more information, see Get-ChildItem for Certificate (https://technet.microsoft.com/library/hh847761.aspx) on MSDN.

-SkipCACheck

Indicates that when connecting over HTTPS, the client does not validate that the server certificate is signed by a trusted certification authority (CA).

Use this parameter only when the remote computer is trusted using another mechanism, such as when the remote computer is part of a network that is physically secure and isolated, or when the remote computer is listed as a trusted host in a WinRM configuration.

Type: SwitchParameter
Parameter Sets: WSManParameterSet
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-SkipCNCheck

Indicates that the certificate common name (CN) of the server does not need to match the hostname of the server.

Use this parameter only for remote operations that use the HTTPS protocol.

Note: Use this parameter only for trusted computers.

Type: SwitchParameter
Parameter Sets: WSManParameterSet
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-SkipRevocationCheck

Indicates that the revocation check for server certificates is skipped.

Note: Use this parameter only for trusted computers.

Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False

-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. 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
Parameter Sets: WSManParameterSet
Aliases: 

Required: False
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
