In the Windows environment, the Close-SmbSession cmdlet is a powerful tool that allows users to close an SMB session established with a remote server. This cmdlet is particularly important for managing network connections efficiently and ensuring proper resource allocation. By understanding how to use Close-SmbSession effectively, users can optimize their PowerShell scripts and commands for managing SMB sessions in a Windows environment.

Examples:

Example 1: Closing an SMB session by session ID

$session = Get-SmbSession -SessionId 12345
Close-SmbSession -SmbSession $session

In this example, we retrieve the SMB session with the session ID 12345 using the Get-SmbSession cmdlet. Then, we pass the retrieved session object to the Close-SmbSession cmdlet to close the session.

Example 2: Closing all SMB sessions to a specific server

$server = "FileServer01"
$sessions = Get-SmbSession | Where-Object { $_.ServerName -eq $server }
Close-SmbSession -SmbSession $sessions

In this example, we use the Get-SmbSession cmdlet to retrieve all SMB sessions and filter them based on the server name. We then pass the filtered sessions to the Close-SmbSession cmdlet to close all sessions to the specified server.

Example 3: Closing all SMB sessions for a specific user

$user = "JohnDoe"
$sessions = Get-SmbSession | Where-Object { $_.UserName -eq $user }
Close-SmbSession -SmbSession $sessions

In this example, we retrieve all SMB sessions using the Get-SmbSession cmdlet and filter them based on the username. We then pass the filtered sessions to the Close-SmbSession cmdlet to close all sessions for the specified user.
