Test-WSMan - PowerShell command help and examples

Tests whether the WinRM service is running on a local or remote computer. (Test-WSMan)


NAME
Test-WSMan
SYNOPSIS
Tests whether the WinRM service is running on a local or remote computer.
SYNTAX
Test-WSMan [[-ComputerName] <string>] [-Authentication <Authentication>] [-Credential <PSCredential>] [<CommonParameters>]
DESCRIPTION
The Test-WSMan cmdlet submits an identification request that determines whether the WinRM service is running on a local or remote computer. If the tested computer is running the service, the cmdlet displays the WS-Management identity schema, the protocol version, the product vendor, and the product version of the tested service.
PARAMETERS
-Authentication <Authentication> Specifies the authentication mechanism to be used at the server. Possible values 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. - 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 negotiation to determine whether the Kerberos protocol or NTLM is used. - CredSSP: Use Credential Security Service Provider (CredSSP) authentication, which allows the user to 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's 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. Important: If the authentication parameter is not specified, then the Test-WSMan request will be sent to the remote machine anonymously (without using authentication). If the Test-WSMan request is made anonymously, it does not return any information that is specific to the operating-system version. Instead, Test-WSMan displays null values for the operating system version and service pack level (OS: 0.0.0 SP: 0.0). Required? false Position? named Default value Accept pipeline input? false Accept wildcard characters? false -ComputerName <string> Specifies the computer against which you want 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. Required? false Position? 1 Default value localhost Accept pipeline input? false Accept wildcard characters? false -Credential <PSCredential> 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, you will be prompted for a password. Required? false Position? named Default value Accept pipeline input? false Accept wildcard characters? false <CommonParameters> This cmdlet supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, WarningAction, WarningVariable, OutBuffer and OutVariable. For more information, type, "get-help about_commonparameters".
INPUTS
None This cmdlet does not accept any input.
OUTPUTS
None This cmdlet does not generate any output object.
NOTES
By default, the Test-WSMan cmdlet queries the WinRM service without using authentication, and it does not return any information that is specific to the operating-system version. Instead, it displays null values for the operating system version and service pack level (OS: 0.0.0 SP: 0.0).

Examples

EXAMPLE 1
C:\PS>test-wsman wsmid : http://schemas.dmtf.org/wbem/wsman/identity/1/wsmanidentity.xsd ProtocolVersion : http://schemas.dmtf.org/wbem/wsman/1/wsman.xsd ProductVendor : Microsoft Corporation ProductVersion : OS: 0.0.0 SP: 0.0 Stack: 2.0
Description
----------- This command determines whether the WinRM service is running on the local computer or on a remote computer.
EXAMPLE 2
C:\PS>test-wsman -computername server01 wsmid : http://schemas.dmtf.org/wbem/wsman/identity/1/wsmanidentity.xsd ProtocolVersion : http://schemas.dmtf.org/wbem/wsman/1/wsman.xsd ProductVendor : Microsoft Corporation ProductVersion : OS: 0.0.0 SP: 0.0 Stack: 2.0
Description
----------- This command determines whether the WinRM service is running on the server01 computer named.
EXAMPLE 3
C:\PS>test-wsman -authentication default wsmid : http://schemas.dmtf.org/wbem/wsman/identity/1/wsmanidentity.xsd ProtocolVersion : http://schemas.dmtf.org/wbem/wsman/1/wsman.xsd ProductVendor : Microsoft Corporation ProductVersion : OS: 6.0.6001 SP: 1.0 Stack: 2.0
Description
----------- This command tests to see if the WS-Management (WinRM) service is running on the local computer using the authentication parameter. Using the authentication parameter allows the Test-WSMan cmdlet to return the Operating System version.

C:\PS>test-wsman -computername server01 -authentication default wsmid : http://schemas.dmtf.org/wbem/wsman/identity/1/wsmanidentity.xsd ProtocolVersion : http://schemas.dmtf.org/wbem/wsman/1/wsman.xsd ProductVendor : Microsoft Corporation ProductVersion : OS: 6.1.7021 SP: 0.0 Stack: 2.0
Description
----------- This command tests to see if the WS-Management (WinRM) service is running on the computer named server01 using the authentication parameter. Using the authentication parameter allows the Test-WSMan cmdlet to return the operating system version.
