In this blog post, we will discuss New-PSSession cmdlet in PowerShell. You can use New-PSSession cmdlet to create a PowerShell session on a local or remote computer. Using New-PSSession cmdlet, you can establish a persistent connection to a local or remote computer using which you can execute scripts, run commands, share data, etc. You can also use “ComputerName” parameter with a supported cmdlet to execute the cmdlet on a remote computer without creating a new PSSession. New-PSSession cmdlet uses PowerShell remoting infrastructure. To use this cmdlet, the local computer and any remote computers must be configured for PowerShell remoting. Below are the prerequisites for using New-PSSession cmdlet.

• Windows PowerShell 2.0 or later
• The Microsoft .NET Framework 2.0 or later
• Windows Remote Management 2.0
• The current user must be a member of the Administrators group on the remote computer or provide the credentials of an administrator.

To configure PowerShell to receive remote commands:

• Start PowerShell with the “Run as administrator” option.
• At the command prompt, type: Enable-PSRemoting

• –ApplicationName: Specifies the application name segment of the connection URI. Use this parameter to specify the application name when you are not using the ConnectionURI parameter in the command.

• –CertificateThumbprint: Specifies the digital public key certificate (X509) of a user account that has permission to perform this action. Enter the certificate thumbprint of the certificate.
• –ComputerName: Specifies an array of names of computers. This cmdlet creates a persistent connection (PSSession) to the specified computer. If you enter multiple computer names, New-PSSession creates multiple PSSession objects, one for each computer. The default is the local computer.
• –ConfigurationName: Specifies the session configuration that is used for the new PSSession.
• –ConnectionUri: Specifies a URI that defines the connection endpoint for the session. The URI must be fully qualified. The format of this string is as follows: <Transport>://<ComputerName>:<Port>/<ApplicationName> The default value is as follows: http://localhost:5985/WSMAN

• –Credential: Specifies a user account that has permission to do this action. The default is the current user.

• –Name: Specifies a friendly name for the PSSession.
• –Port: Specifies the network port on the remote computer that is used for this connection. To connect to a remote computer, the remote computer must be listening on the port that the connection uses. The default ports are 5985, which is the WinRM port for HTTP, and 5986, which is the WinRM port for HTTPS.
• –RunAsAdministrator: Indicates that the PSSession runs as administrator.
• –Session: Specifies an array of PSSession objects that this cmdlet uses as a model for the new PSSession.
