Test whether the WinRM service is running on a local or remote computer.
Syntax Test-WSMan [[-ComputerName] string] [-Authentication Authentication] [-Credential PSCredential] [CommonParameters] Key -Authentication Authentication The authentication mechanism to be used at the server. Possible values are: Basic Send username and password in clear text. Default Use the authentication method implemented by WS-Management protocol. This is the default. Digest Challenge-response scheme using a server-specified data string for the challenge. Kerberos Authenticate by using Kerberos certificates. Negotiate Challenge-response that negotiates an authentication scheme. e.g. Kerberos protocol or NTLM. CredSSP Use Credential Security Service Provider (CredSSP) authentication, delegate credentials to a remote computer. This increases the security risk, if the remote computer is compromised, the credentials could be used to control the network session. -ComputerName string The computer against which you want to run the management operation. A fully qualified domain name, NetBIOS name, or an IP address. Use the local computer name, localhost, or a dot (.) to specify the local computer. The local computer is the default. When the remote computer is in a different domain, use a fully qualified domain name. You can pipe a value for ComputerName. -Credential PSCredential A user account that has permission to perform this action. default=current user. e.g. "User01", "Domain01\User01", or "User@Domain.com". Or a PSCredential object, such as returned by the Get-Credential cmdlet. When you type a user name, you will be prompted for a password. CommonParameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -WarningAction, -WarningVariable, -OutBuffer -OutVariable.
If the tested computer is running the WinRM service, Test-WSMan will display the WS-Management identity schema, the protocol version, the product vendor, and the product version of the tested service.
Determine whether the WinRM service is running on the local computer:
PS C:> test-wsman
Determine whether the WinRM service is running on server64 :
PS C:> test-wsman -computername server64
Test to see if the WS-Management (WinRM) service is running on the local computer using the authentication parameter, this allows Test-WSMan to return the Operating System version:
PS C:> test-wsman -authentication default
