Get SmbSession - PowerShell

Overview

Get-SmbSession retrieves information about active Server Message Block (SMB) sessions on the local computer. It provides insights into current SMB connections, allowing administrators to troubleshoot network connectivity issues, monitor user activity, and identify potential security concerns.

Syntax

Get-SmbSession [-ComputerName] <String> [-SessionId] <Int32[]> [-UserName] <String> [-Path] <String> [-Status] <SMBStatus[]> [-OpenFiles] [-IncludeHidden] [-IncludeServer] [-WaitTime] <Int32> [-Force] [-OutVariable] <String>

Options/Flags

  • -ComputerName: Specifies the target computer to retrieve SMB session information from. Defaults to the local computer.
  • -SessionId: Filters results by specific SMB session IDs.
  • -UserName: Filters results by the username associated with the SMB sessions.
  • -Path: Filters results by the path to the shared resource being accessed via SMB.
  • -Status: Filters results by the status of the SMB sessions (e.g., Active, Inactive, Closing).
  • -OpenFiles: Includes information about open files within the SMB sessions.
  • -IncludeHidden: Includes hidden SMB sessions in the results.
  • -IncludeServer: Includes server-side SMB sessions in the results.
  • -WaitTime: Specifies the time in seconds to wait for SMB server responses.
  • -Force: Forces the retrieval of all SMB sessions, even if the server does not support it.
  • -OutVariable: Stores the results in a variable for further processing.

Examples

Example 1: Lists all active SMB sessions

Get-SmbSession

Example 2: Filters sessions by username and status

Get-SmbSession -UserName "John Doe" -Status Active

Example 3: Retrieves server-side SMB sessions

Get-SmbSession -IncludeServer

Common Issues

  • Permission Denied: The command requires administrative privileges on the target computer.
  • No Results: Ensure that SMB sessions are active on the target computer and that the filters used are appropriate.
  • Slow Retrieval: Allow sufficient wait time (-WaitTime) for server responses, especially for large-scale environments.

Integration

  • Use Set-SmbSession -Status Inactive to disconnect specific SMB sessions.
  • Combine with Get-NetSession to gather additional network session information.
  • Use scripting to automate SMB session monitoring and reporting.
  • Get-NetSession
  • Set-SmbSession
  • Remove-SmbSession
