    When you install a network or start to work in the Internet or your intranet, it becomes clear to find monitoring and management software ASAP. Why? Because of possible delays or bottlenecks of Internet traffic. The number of applications is a blessing, given the fact that every company and every sysadmin have different needs, which would make a one-size-fits-all approach difficult to implement.

    Most network software comes with some level of monitoring and management capability, but often IT departments appreciate being able to choose different features. Here is a rescue wand - NetInfo. This multifunctional application analyzes your connection and various aspects of the Internet in order to isolate potential pitfalls. Once it determines where the problem lies, NetInfo provides you with a whole slew of tools that help you solve it. If the problem lies beyond your realm of control and you don't know whom to contact about it, NetInfo will give you a name, e-mail address and phone number. Instead of gathering the information about a host and the Internet route to it manually, you just enter a hostname and click Start. NetInfo does the rest for you. By the way, it allows finding spammers, tracing hackers, hunting mailers and porno promoters.

    There are some key features of the program:

    * Allows to you quickly verify network connectivity to another IP address on the network * Displays a list of routers between your system and the destination system * Displays information about users currently logged on to a specified server * Scans host names for a particular range of IP addresses and displays the state of each address * Lists the available network services - HTTP, Telnet, DNS, SMTP, etc. - for a particular host * Multi platform: one installation runs on Windows 95, Windows 98, Windows Me, Windows NT, Windows 2000, Windows XP, and Windows Server 2003 * Developed in C++ for maximum efficiency

    If your website, a client's site, a mail server or some other Internet point is having trouble, it's up to NetInfo tools to fix it. You've never been in as much control of your and your clients' Internet experience as when you own NetInfo. It becomes possible to retrieve and debug an HTML for a specific page on the Web.
