Inventory computers on a network in a few minutes with Total Network Inventory! Total Network Inventory is a PC Audit and Network Inventory program for office and large scale enterprise networks.

Total Network Inventory interrogates all PC's on a network and reports back with complete information about OS, service packs, hotfixes, hardware, software, running processes, etc. on remote machines. This information is added to a centralized database and network administrators are able to generate reports about each or all PC's on a network.

The program is agent-free and requires no special software installed on remote machines. Total Network Inventory has been designed with the user in mind, which is reflected in its interface that provides quick and unobtrusive navigation throughout the program.

Total Network Inventory starts with a Welcome window with six large, image-coded buttons: "Run Scan Wizard", "Scan this PC", "Show Main Window", "Scan Other PC", "Visit product homepage", and "View help contents". Depending on what you want to do, you simply click on the required button and immediately find yourself in that section of the program.

Total Network Inventory includes a Report Builder, which lets you generate reports with just a few clicks. Reports are great because they present the information about networked machines in an easy to read and understand manner. Report Builder allows you to generate a report on any topic that interests
you ("Single category report"). For example, you can create a report with the information about a network adapter, IP-addresses, MAC-addresses, DHCP, DNS and WINS settings for any number of computers.

General information
wodDHCPServer is a DHCP server component (Dynamic Host Configuration Protocol), available as COM object and ActiveX control. It provides a framework for passing configuration information to hosts on TCP/IP network. wodDHCPServer implements protocol specific infrastructure, allowing you to allocate IP addresses from your address pool, and provide it to requesting clients by your rules. It is configurable by set of objects and events where you can add your code to control component's behavior.


How does it work?
As described in RFC2131, when clients connect to the network for the first time, they will Announce themselves to the network, waiting for all DHCP servers on the network to send their Offers for possible IP addresses (and other network parameters). Once they receive this information, clients can choose among received offers, and Request the IP address from your server. At any point, based on your decisions, you can Accept client's requests, or just Deny them. At all times, you should keep a database of your address pool, allocations and released done by your server.

Each request received from the client gets unique Session object, where session specific data is stored. You will find here client's MAC address (usually your choices will be based on this information), and setup network parameters directly by populating this object information (Hostname, Gateway...).


Availability
wodDHCPServer can be used from any programming language that supports COM or ActiveX controls. You will find provided samples in VB and VC, but you could also use it in .NET framework, and other languages such as FoxPro.

Switch network settings on your laptop/notebook. Ideal for laptop/notebook users, who travel from one network location to another. It switches a computer between multiple network configurations (profiles) with one click of a button. A profile can include LAN-settings (IP-address, DNS, gateway), your browser's proxy settings (supports Internet Explorer, Firefox and Opera), Windows Firewall settings, network drive mappings, default printer, SMTP-server and more.

For example you can switch from a static to a DHCP assigned IP address, or switch one static IP address to another.

Use your laptop/notebook on multiple networks: assume you have a DHCP-enabled network at your office, and a static IP-address assigned to your network card at home. Every time you connect your notebook or laptop to a new network, you have to change network adapter settings manually. But, wouldn't it be easier to store two profiles (called "office" and "home") and switch between these two profiles? If you deal with two or more locations, you can benefit from this net switcher utility which creates a profile with your configuration settings: TCP/IP-settings, browser-proxy (Firefox-compatible, Opera-compatible), network drives, default printer settings, SMTP server address etc. Then you can easily switch between locations by activating a profile.
