Advanced LAN Scanner
If you're a techie and have more than one PC at work or home on a network sharing a single Internet connection, you'll welcome this freebie, which offers surprisingly powerful scanning capabilities. Use it for everything from troubleshooting Internet connections, to network configuration, to making sure your PCs are as safe as possible when they're on the Internet.
When you first run the program, you may encounter an error message, saying that a default configuration is being used. You can safely ignore that message. Simply click the scan button, and it goes to work. It looks across your network, finds all PCs on it, and then gives you quite a bit of detail about each. Besides the local IP address of each PC, you'll also find which ports on each PC are open. Armed with that information, you can use a firewall to close them down.
In addition to open and closed ports, you'll see lots more information, such as what services are running on each PC, the NetBIOS names (if any) associated with each, and even a list of users and groups on each system. If any machines have shared folders, you'll see those as well. All this data is immensely useful to those who want to keep their PCs secure, or need to troubleshoot networks or Internet connections.
Making the software all the more remarkable is that it's free.

FileZilla
One of the Internet's oldest file-transfer protocols – FTP – still lives. Contrary to popular wisdom, not all files are downloaded from Web sites. Many are still downloaded from FTP servers. And many individuals and businesses continue to use FTP as a way to share files. Also, many ISPs block large files, so using FTP is a great way around that problem.
FileZilla is an excellent FTP client that combines simplicity with a robust feature set (it has just about every FTP feature you could need), and its interface is easy to use.
