A network or network infrastructure is the grouping of hardware devices and software components needed to connect devices within an organization and to connect the organization to other organizations and the Internet.

The Terminal Services Manager tool (Tsadmin.exe) is the main administration tool used to manage existing Terminal Services sessions, users, and processes that are connected to or running on the Terminal Services server. The Terminal Services Manager tool can manage one or more Terminal Services servers.

In order for clients to establish Terminal Services sessions on a server, listener connections have to be configured on the particular server. A listener connection can be configured for only RDP (Remote Data Protocol) over TCP/IP. One listener connection can be configured for a network interface card (NIC) in the Terminal Services computer.

An Introduction to Fault Tolerance
The following issues initiate downtime:
Hardware Failures: Hardware failures can be described as failures that occur in mechanisms like disks or storage media. Hardware failures tend to offset other failures.

Automated System Recovery (ASR) Overview

Microsoft Cluster Service Overview
A cluster is the grouping of two or multiple physical servers that are perceived to the network as one network server.

Monitoring Server Performance and Activity
One of the basic steps to optimizing server performance is to monitor server performance. To optimize server performance, you can perform a number of tasks, such as:

Reducing the load of network traffic on the particular server by implementing load balancing strategies.
