However, Windows security has so many different components that just learning them all can be a major conceptual challenge. Additionally, the number and variety of threats to computer security are increasing daily, and the cost of lost, damaged, or compromised data can be very high. This briefing lays out the main security features in the Windows 2003 operating system family, and puts them all into a “big picture” context. It is intended for any person who must plan, implement, manage, or administer Windows 2003 family security for networked desktop computers, notebook computers, or stand-alone systems. It is not intended as an exhaustive treatment of all the possible security breaches that a Windows network administrator may face, but rather as a framework for understanding, planning, and discus...

Network topology is one of the very important topics to learn when it comes to build up computer network. There are many Network Topologies on which network administrator decide to build the network on. Topology is basically defined as layout or design of network, and computers are connected using the design of the topology. These topologies can be either physical or logical design. Physical topology refers to physical design of network which includes devices, cables, location and installation of network where as in logical topology it is the amount of data to be transferred with in the network as apposed in its design. There are five different Networking Topologies : a) Bus b) Star c) Ringd) Mesh e) Tree. When networks are design using multiple topologies it is called Hybrid Networks, this concept is usually utilized in complex networks were larger number of computer clients are required. Bus Topology Bus topology is one the easiest topologies to install, it does not require lots of ...

Networks are all about sharing resources of computers, servers, printers, scanners etc to each other. There are two different types with which network between computers can be formed. Networking formation completely depends on the requirement of the organization scale and usability. We should always study requirements and needs before we decide to choose any type of network. Picking wrong set of options can cost you waste of money, time and resources.Two types of networks are Peer to Peer networking also known to be p2p, the other one is Client and Server networks. Peer to peer (p2p) P2p networking type is most commonly used computer networks. This type of network is very cost effective but supports lesser number of computers in network. Ten to fifteen computers can be connected to each other using p2p networking model without problem, more number of computers often create problems. All computers possesses same status within the network and no computer control any other computer bu...

This vidoe tutorial describes how to set up a DHCP server (ISC-DHCP) for your local network. DHCP is short for "Dynamic Host Configuration Protocol", it's a protocol that handles the assignment of IP addresses, subnet masks, default routers, and other IP parameters to client PCs that don't have a static IP address. Such computers try to find a DHCP server in their local network which in turn assigns them an IP address, gateway, etc. so that they can connect to the internet or other computers from the local network.
