Retrieve the connections established from the SMB client to any SMB servers.
Users can connect to an SMB share using credentials different than the associated logon credentials so that there will be a connection listed per share per user logon per credential used.

      Get-SmbConnection [[-ServerName] String[]] [[-UserName] String[]] [-CimSession CimSession[]]
         [-SmbInstance {Default | CSV}] [-ThrottleLimit Int32] [CommonParameters]

   -CimSession [CimSession[]]
       Run the cmdlet in a remote session or on a remote computer.
       Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet.
       The default is the current session on the local computer.

       Specifies that the connections made to the server are enumerated.

       Specifies the input to this cmdlet. You can use this parameter, or you can pipe the input to this cmdlet.

   -ThrottleLimit [Int32]
       The maximum number of concurrent operations that can be established to run the cmdlet.
       If this parameter is omitted or a value of 0 is entered, then PowerShell will calculate an optimum throttle limit 
       for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies 
       only to the current cmdlet, not to the session or to the computer.

       Specifies that the connections made by the user are enumerated.
