Lansweeper's core functionality is discovering and pulling data from the assets in your network. Lansweeper can scan Linux, Unix, Mac and Windows computers, VMware servers and other network devices like printers and switches. Network scans are performed by one or more Lansweeper scanning servers, which are machines that have the Lansweeper Server service installed. In order for a scanning server to access the network and pull data from your assets, it must of course have a network interface enabled. If no interface is enabled, you will not be able to scan your IP ranges. You will also see a warning similar to the one below in your Lansweeper web console's First Run Wizard upon installing and opening Lansweeper for the first time.
To resolve this warning and successfully scan an IP range, do the following:
- On your Lansweeper server, open your Start menu and select Run.
- In the input box, type ncpa.cpl and hit OK. This opens the Network Connections menu and shows you the network interfaces your scanning server has available.
- If your scanning server does have a network interface available that is currently disabled, right-click it and choose Enable.
- If your scanning server does *not* have a network interface available, do the following to add one:- Open your Start menu and select Run.- In the input box, type hdwwiz.exe, hit OK and then Next in the popup window.- Select Install the hardware that I manually select from a list (Advanced) and hit Next.- Select Network adapters and hit Next.- Wait for the screen to load.- Choose a network adapter for installation. Ideally, your scanning server has a physical network adapter and you can simply select the adapter that matches your hardware. In the example below, we are just installing the Microsoft Loopback Adapter. This will only allow us to scan the scanning server itself but will still give us a feel for the type of scanning Lansweeper can perform. Hit Next and then Next again.
- Restart the Lansweeper Server service in Windows Services.
- Refresh the web browser tab that was displaying the First Run Wizard. The warning message should now be gone and you should be able to select an IP range for scanning.
