How to Use EMCO WakeOnLan Professional: Step-by-Step GuideEMCO WakeOnLan Professional is a Windows tool that lets you remotely power on, wake up, and shut down computers over a local network or the Internet. This guide walks through installation, configuration, discovery of machines, sending Wake-on-LAN (WOL) packets, scheduling, remote shutdown, troubleshooting, and best practices so you can manage power for multiple PCs effectively.
What you’ll need before starting
- A Windows machine to run EMCO WakeOnLan Professional (Windows 7 and later; check current compatibility if using server editions).
- Target computers with Wake-on-LAN support enabled in BIOS/UEFI and their network adapters configured accordingly.
- Administrative credentials for target machines if you plan to use remote shutdown or advanced management.
- Proper network configuration (router/switch allowing UDP magic packets and, if over the Internet, port forwarding or VPN).
1. Install EMCO WakeOnLan Professional
- Download the installer from EMCO Software’s official website.
- Run the installer and follow prompts. Choose the installation folder and accept license terms.
- Launch the application after installation completes. If you have a license key, enter it to activate the Professional features; otherwise you can first explore the trial mode.
2. Configure application settings
- Open the Settings/Options panel.
- Set a default timeout and retries for network operations.
- Configure the network interfaces EMCO should use if the host has multiple NICs.
- Adjust discovery parameters (IP ranges, timeouts) to suit your network size.
- If you plan to wake machines over the Internet, configure the external broadcast address or the gateway IP and the UDP port (default 9 or 7). Ensure your router forwards that port to your internal network if needed.
3. Enable Wake-on-LAN on target machines
- BIOS/UEFI: Enter each target PC’s BIOS/UEFI and enable Wake-on-LAN (may appear as “Wake on PCI/PCIe,” “Power on by LAN,” or similar).
- Network adapter (Windows):
- Open Device Manager > Network adapters > Properties of the NIC > Power Management.
- Check Allow this device to wake the computer and Only allow a magic packet to wake the computer (optional but recommended).
- Under the Advanced tab, enable settings like Wake on Magic Packet, Wake From Shutdown, or vendor-specific options.
- Ensure the OS shutdown state still supports WOL (S3/S4/S5 behavior depends on motherboard and NIC).
4. Add computers to EMCO WakeOnLan Professional
- Manual entry:
- Click Add > New Computer.
- Enter the computer name or description, MAC address (required for WOL), IP address or hostname, and optionally the subnet and group.
- Save the entry.
- Discovery:
- Use the Discover or Scan feature. Input an IP range or network segment.
- EMCO will scan and populate discovered hosts with available info (name, IP, MAC).
- Review discovered entries and add them to your list.
- Import:
- Import from CSV or AD (if supported in your edition). Provide a CSV with columns such as name, IP, MAC, and group.
5. Organize your inventory
- Create groups (by office, floor, department) and drag computers into groups for easier management.
- Use tags or descriptions to add location, owner, or purpose.
- Save views and filters for quick access to commonly managed sets.
6. Wake computers (send magic packets)
- Select one or multiple computers in the list or a group.
- Click Wake (or Send Magic Packet). EMCO will build and send a magic packet to each selected machine’s MAC address using the configured broadcast method.
- Monitor the status column — EMCO will show whether the host responded or stayed offline.
- If waking over subnet boundaries, ensure correct broadcast or gateway settings and that intermediate routers allow directed broadcasts (often disabled by default).
7. Remote shutdown, restart, and other actions
- To shut down or restart remote machines, select them and choose Remote Shutdown or Restart.
- Provide administrative credentials when prompted. You can save credentials in the application for repeated use (consider security policies before storing credentials).
- You can also send custom commands, run scripts, or trigger remote actions (depending on Professional edition features and permissions).
8. Schedule wake and shutdown tasks
- Open the Scheduler or Tasks section.
- Create a new task: choose action (Wake, Shutdown, Restart), target machines or group, recurrence (one-time, daily, weekly), and time.
- Configure pre- and post-conditions (e.g., only run if the host is offline for Wake tasks).
- Test scheduled tasks with a shorter schedule to confirm behavior.
9. Using Wake-on-LAN across the Internet
- Prefer VPN for security and reliability: connect remotely to the LAN via VPN, then use EMCO as if local.
- If VPN isn’t available:
- Configure your router to forward the chosen UDP port (commonly 9 or 7) to the broadcast address or a dedicated internal IP. Many routers block directed broadcasts; alternative is to forward to a WOL helper device.
- In EMCO, set the external gateway or broadcast IP and port. Use the public IP of the network when awake from the Internet.
- Be aware of security risks when exposing WOL ports; restrict access where possible and use strong router rules.
10. Troubleshooting common problems
- Computer doesn’t wake:
- Verify MAC address is correct.
- Check BIOS/UEFI WOL setting and NIC power settings in Device Manager.
- Ensure the machine’s power state supports WOL (some systems disable WOL in full shutdown).
- Confirm correct broadcast address and that routers/switches permit the magic packet.
- Discovery fails:
- Ensure firewall rules allow EMCO’s scanning traffic (UDP/TCP as required).
- Try scanning a smaller IP range to isolate network issues.
- Remote shutdown fails:
- Confirm administrative credentials and that Windows Remote Service (Remote Registry, RPC) are available.
- Check target firewall settings for remote management.
11. Security and best practices
- Use VPN rather than exposing WOL ports when possible.
- Restrict who can access EMCO and store credentials securely.
- Keep EMCO and network drivers/firmware updated.
- Test WOL settings during maintenance windows to avoid accidental disruptions.
- Document MAC addresses and WOL-related BIOS/NIC settings for each machine.
12. Advanced tips
- Use grouping and tags to perform bulk operations safely (e.g., wake only a specific floor).
- Combine scheduled WOL with maintenance scripts to run updates during off-hours.
- Monitor logs to verify scheduled tasks and manual operations; export logs for audits.
- If WOL over Wi‑Fi is needed, check vendor-specific support — many wireless NICs and AP setups do not support WOL from a powered-off state.
Troubleshooting checklist (quick):
- Confirm MAC, BIOS, NIC WOL settings.
- Check broadcast/gateway settings and router forwarding if across subnets.
- Verify firewalls and services for discovery and remote shutdown.
- Use VPN for cross-network operations whenever possible.
If you want, I can:
- Create a short checklist you can print and take to each machine for setup.
- Write step-by-step BIOS/NIC setting instructions for a specific motherboard or NIC model. Which would you prefer?
