Advanced IP Scanner 

Advanced IP Scanner is a Windows program that might prove to be of good use to network administrators. With its help, you can identify all of the devices that are being connected to your LAN network and gives you access to shared folders within moments.

In my testing, the application immediately completed the scanning process and revealed detailed information in its main screen. The report can then be exported to 3 file formats: XML, HTML or CSV.

Another advantage is that the utility comes with a powerful search tool that helps you quickly find the connected device within the offered scan results list.

In the Actions menu you will find various tools which can be used to shut down certain devices in your network, access shared folders, and so much more. However, if you're an inexperienced Windows user, I'd suggest you to avoid using these tools until you learn how to use them. The program lacks a built-in help guide, but you can find the info you need on its homepage.

In conclusion, you should try this program if you know a few things about network administration. Advanced IP Scanner works flawlessly, offers you accurate info, and is free.
