1Introduction
The subject of this dissertation is to present a series of measures, to manage the LAN network based on Windows environment by assessing its performance and knowledge of person responsible for its administration. Essential matter will be to understand that most often it is the software which monitors the operation of all devices located within the enterprise network infrastructure, where administrator only analyses the data based on already obtained knowledge. We’re going to outline the primary tasks facing each administrator which are: supervision of the connectivity received by computers via a network, the transmission of messages, routes planning and elimination of the burden to other networks, ensuring network integrity and security, removal of accidental consequences. Distribution of user access and other resources are aimed at efficient operation of the network and its flawless work which are in responsibility of the IT person. At the same time, an administrator should acquaint himself with the details of the existing and emerging standards to manage the network as efficient as possible. In Chapter 1 we’re going to familiarize the reader with the subject about ways to manage the network and we’ll present the architecture of systems that are used to manage the LAN. We are going to briefly explain the network protocol called SNMP in Chapter 2, which is associated with this subject and give examples of implementations and applications on Windows based environment while explaining the efficient use in Chapter 3. By understanding that computer networks and distributed data processing systems are becoming increasingly important, data management and infrastructure are getting complex in many institutions. We’ll realise that computer networks increase the number of applications and users operating simultaneously within the same data. All this is correlated to the result of growing size of networks with its...
