Internet Lock - Protected Internet Access
Internet Lock can be used to password protect the
internet access. You also can use Internet Lock to deny access to any
TCP port, or prevent any program from accessing internet.Internet Lock
is an access control and password protection software for your Internet
and intranet connections, it can deny or password protect any program to access the Internet/intranet on any TCP/IP port. Internet Lock works with the "RULES" mode: you can add one or more rules to the software to control its works.

What it does: Although we strongly recommend you use the previous program to set up your network before firing up UltraVNC, you can use this awesome networking application to connect to any computer with an IP address. Once connected, you're looking and interacting with the computer's desktop as if you were sitting right in front of it. You can also establish file transfers, chat with whoever it is might be sitting at the terminal, and utilize a variety of compression mechanisms to maximize your session's performance regardless of what speed of connection you're using. A number of "VNC" varieties exist on the Interweb, but we have found the most success (and usefulness) with UltraVNC. 
What it does: So you liked UltraVNC, but you have more than one computer you're planning on connecting to at once? No need to fire up a bunch of UltraVNC sessions--not when you have terminals, that is. This is the tabbed browsing program we mentioned previously. It's a great way for the hardcore network enthusiast to manage multiple networked screens at once, and it comes with a bunch of system administrator network tools built into the application for easy access. You never know when you might need a Trace Route... 
What it does: Live Mesh lets you pull off the same remote desktop features as Terminals and UltraVNC, but the true strength of this application lies in its powerful synchronization features. You create a mesh, which is a grouping of computers and users who all receive special access to a batch of files. To create this batch, you assign folders on your computer to serve as Mesh Folders--anything placed in them gets synchronized to the devices in your Mesh. It's a great way for keeping your files and folders organized across multiple devices--even better if you and your friends like to share a hot batch of jams amongst each other. 
The name of this application should give away its features, but there's more to this helpful program than you might think. Not only will it scan through a class of IP addresses and tell you details about all the computers it sees, but it lets you perform simple--but powerful--commands on the network devices you find. Throw them wake-on-LAN commands, shut them down remotely, and connect to the computers (via Radmin) at the touch of a button. If you're running a large network of PCs, put this program on your "to-install" list immediately.
