Get-SmbConnection

Retrieves the connections established from the SMB client to the SMB servers.
Get-SmbConnection [[-ServerName] <String[]>] [[-UserName] <String[]>] [-CimSession <CimSession[]>] [-SmbInstance{Default | CSV}] [-ThrottleLimit <Int32>] [<CommonParameters>]

The Get-SmbConnection cmdlet retrieves the connections established from the Server Message Block (SMB) client to the 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.

Parameters

-CimSession [<CimSession[]>]

Runs 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.

-ServerName [<String[]>]

Specifies that the connections made to the server are enumerated.

-SmbInstance [<Microsoft.PowerShell.Cmdletization.GeneratedTypes.SmbShare.SmbInstance>]

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

-ThrottleLimit [<Int32>]

Specifies 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 Windows PowerShellr calculates 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.

-UserName [<String[]>]

Specifies that the connections made by the user are enumerated.

<CommonParameters>

This cmdlet supports the common parameters: Verbose, Debug,ErrorAction, ErrorVariable, WarningAction, WarningVariable,OutBuffer, PipelineVariable, and OutVariable.

Inputs

Outputs
Microsoft.Management.Infrastructure.CimInstance#root/Microsoft/Windows/SMB/MSFT_SmbConnection

    ContinuouslyAvailable : True Credential            : Contoso\Contoso-HV1$ Dialect               : 3.00 Encrypted             : False NumOpens              : 1 ServerName            : Contoso-FS ShareName             : VMS1 UserName              : Contoso\Contoso-HV1$ PSComputerName        : CimClass              : ROOT/Microsoft/Windows/SMB:MSFT_SmbConnection CimInstanceProperties : {ContinuouslyAvailable, Credential, Dialect, Encrypted...} CimSystemProperties   : Microsoft.Management.Infrastructure.CimSystemProperties
    
       ContinuouslyAvailable : True 
       Credential            : Contoso\Contoso-HV1$ 
       Dialect               : 3.00
