Windows 7 Ghost listed on network overview

[stonefox]

Network overview shows the unit I do not want to recognize.
When I look in Explorer "Network" I've got a new called "ONAL" and I do not know where came from.
As shown in the image I get an empty list when I choose "Open in New Window" and an error if I try to "Connect to Remote Desktop"
How do I remove this "ghost"? or locate what it is?

The appearance of a network device named "ONAL" in your network overview that you didn't recognize can be concerning. Here are steps you can take to investigate and remove this unidentified network device:

Steps to Identify and Remove the Unknown Network Device "ONAL":​

1. Network Discovery:
   • Check if any new devices have been connected to your network recently. This could be a physical device or even a virtual network.
   • Ensure that all your devices are secure and that unauthorized access is not possible.
   []Check Network Devices:
   • Navigate to your Network and Sharing Center to view connected devices.
   • Review the list to see if "ONAL" appears in the list of network devices. If it does, right-click on it to see properties or try to remove it from the network.
   []Check Router Settings:
   • Log in to your router's administration panel using a web browser.
   • Look for a section that shows connected devices or DHCP clients. Check if "ONAL" appears in this list. You may be able to block or remove it from here.
   []Use Command Prompt:
   • Open Command Prompt as an administrator.
   • Use the command ipconfig /all to view the network configuration of your device. Look for any unexpected connections or adapters.
   []Run Network Scans:
   • Use network scanning tools like Nmap or Advanced IP Scanner to scan your network for connected devices. This can help you identify any unknown devices.
   []Check Windows Firewall:
   • Verify that the Windows Firewall is active and configured correctly to prevent unauthorized access.
   []Remove Unknown Device:
   • If you find the device listed in your network, you may be able to remove it by right-clicking on it and selecting the option to remove or forget the device.
2. Security Measures:
   • Change your Wi-Fi password to prevent unauthorized access.
   • Consider enabling MAC address filtering on your router to restrict which devices can connect to your network. By following these steps, you can investigate the presence of the unknown network device "ONAL" in your network and take appropriate actions to remove or secure your network from unauthorized access.
