Enter PSSession - PowerShell

Overview

Enter-PSSession establishes a remote PowerShell session with a target computer or session configuration, allowing you to run commands and manage resources remotely. It’s ideal for managing multiple systems, automating tasks, and troubleshooting issues from a centralized location.

Common Issues

  • Ensure network connectivity between the local and remote systems.
  • Verify that the remote session is configured to allow external connections.
  • Use the -Authentication parameter to specify the correct authentication method for your environment.

Integration

Combine with Invoke-Command: Execute commands remotely using the Invoke-Command cmdlet within an Enter-PSSession session.

Use with DSC: Manage Desired State Configuration (DSC) resources in remote systems by establishing a session with the DSCPullServer role.
