NAME
Test-WSMan

SYNOPSIS
Tests whether the WinRM service is running on a local or remote computer.

SYNTAX
Test-WSMan [[-ComputerName] ] [-Authentication ] [-Credential ] [ eters>]


DESCRIPTION
The Test-WSMan cmdlet submits an identification request that determines whether the WinRM service is running on a l
ocal or remote computer. If the tested computer is running the service, the cmdlet displays the WS-Management ident
ity schema, the protocol version, the product vendor, and the product version of the tested service.


PARAMETERS
-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 th
e 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 i
ncreases 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 re
mote machine anonymously (without using authentication). If the Test-WSMan request is made anonymously, it doe
s not return any information that is specific to the operating-system version. Instead, Test-WSMan displays nu
ll 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
Specifies the computer against which you want to run the management operation. The value can be a fully qualifi
ed 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 do
main 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
Specifies a user account that has permission to perform this action. The default is the current user. Type a us
er 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


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 retur
n any information that is specific to the operating-system version. Instead, it displays null values for the op
erating system version and service pack level (OS: 0.0.0 SP: 0.0).


-------------------------- 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 authentic
ation parameter.

Using the authentication parameter allows the Test-WSMan cmdlet to return the Operating System version.





-------------------------- EXAMPLE 4 --------------------------

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.
