These ten downloads, most of them free and none of them expensive, will make managing your small network much easier.
1. Network Magic Essentials and Network Magic Pro
Anyone who has a home network will welcome Cisco Systems' free Network Magic Essentials, a software collection full of useful tools designed for home network users who don't have IT experience. You'll find a network map for displaying all of the devices on your network, and vital information about each one, including its IP address, hardware configuration and software configuration. You also get some very good troubleshooters for fixing broken network connections and performing other maintenance tasks.
If you manage a work-related network, you may want to step up to Network Magic Pro. In addition to including all of the Network Magic Essentials tools, it offers support for a larger number of PCs and for network attached devices, and it provides ways to control Internet access. The Pro version also makes available some excellent network security tools and a network history report that shows bandwidth use by computer.
2. Spiceworks IT Desktop
Here's another free, all-in-one network management tool. Spiceworks' IT Desktop is browser-based and offers lots of details about each device on your network: free space, total disk space, what antivirus software is in use and even server connection errors, among other information. IT Desktop is harder to use than the Network Magic programs, but its advanced features make it more useful for IT professionals. It also provides an inventory of software on each PC. There's even a Help Desk ticket system for IT staff.
3. Network Scanner
For a quick and simple way to assemble an inventory of all of the devices attached to your network, and to find vital information about each one of them, Network Scanner by LizardSystems is hard to beat. The utility scans your entire network, and then provides details, including IP addresses, about all of the devices. Network Scanner is particularly helpful if you're concerned about security, because it reports whether remote administration is enabled. The program also lists any publicly shared folders, so you can quickly identify security holes and then close them.
4. Netbrute Scanner
Raw Logic Software's Netbrute Scanner is an extremely useful tool for people who want to test their network's security. It scans all of the computers on a network, and then looks for security holes such as open TCP ports, installed software such as servers and FTP software, and shared folders and resources. Based on what you find, you can reconfigure each PC. Though the vendor's site doesn't list this software as working with Windows 7, I was able to run it on Windows 7 without a hitch.
5. Bandwidth Monitor 2 lite edition
Once you've installed Rokario's free Bandwidth Monitor 2 Lite Edition on any PC on your network, it will track bandwidth use in real time. The program displays download bandwidth use, upload bandwidth use, and total bandwidth. It also keeps logs of bandwidth use, so you can retain a historical record.
Install it on every PC on your network and then check the results, especially the historical records of bandwidth use, regularly on each PC. That way, you can see whether any bandwidth hogs are wallowing on your network. Based on that, you can try to reduce its excess demand... maybe too much YouTube?
6. LAN Speed Test
Another useful bandwidth and speed tool, Totusoft's LAN Speed Test checks the real upload and download speeds of the network on the PC where it is installed. Load it on every PC on your network, and run it regularly on each one. That way, you can see whether any PCs are having speed problems that may require intervention.
7. InSSIDer 2
The free InSSIDer 2 from MetaGeek helps solve this thorny problem. It searches out every wireless network in an area, shows the signal strength of each, and shows the channels that each one uses. That way, you can determine whether a nearby network might be generating interference and change your channel.
You can also walk around your office or home with InSSIDer on a laptop, and see the signal strength in all locations, to find dead spots. Then you can solve the problem either by moving your router or by moving the PC from the poorly served location.
8. Xirrus Wi-Fi Inspector
A similar tool for troubleshooting wireless networks, Xirrus Wi-Fi Inspector offers even more information than InSSIDer does about each wireless network it finds. You can get information about your wireless network to make sure it's properly configured, for example, pinging your configured DNS server and gateway to confirm that they're active and working properly. A network speed tester lets you test the speed of your wireless network, too. The vendor's site for this software doesn't list it as working with Windows 7, but I ran it on Windows 7 without any problems.
9. Technitium MAC Address Changer
Have intruders slipped into your network, or are your security tools working well? Technitium MAC Address Changer can help you find out. Let's say that you use MAC address filtering to ban all devices from your network except those that use specific MAC addresses. You can use Technitium MAC Address Changer to give any PC a new MAC address not normally allowed in your network, and then see whether you can evade detection by your established network security and sneak onto the network while using the new MAC address. If you can't find a way to slip in, your network is all set. If you can, that should serve as a strong signal to you that it's time to update your security.
10. Find MAC Address
Another great MAC address tool, LizardSystems' Find MAC Address scans every device on your network and then reports on their MAC addresses. It even finds mobile devices such as tablets. Use the tool first to create an inventory of MAC addresses for devices that you know should be on the network, then use Find MAC Address regularly to determine whether any unauthorised devices are using the network.
