What is a Network Monitor For?

Network equipment failures can cause grave consequences, such as material and data looses, bad relations with your customers, etc. System administrators should monitor their networks constantly, detect all the failures that can occur on all network devices (local computers, servers, switches, network printers and others) in time, and recover them as fast as possible. That is why the network monitoring is vital in modern IT infrastructure. iPod Developer

With a network monitoring program, a system administrator can solve the uptime problem effortlessly. The application is to be installed on the administrator's computer or a server and should operate 24 hours 7 days a week. The monitoring process should run remotely via a network.

An advanced monitoring program should contain a wide set of checks that allow the administrator to be notified about any network failures. The program should help you to check the state of any device or server in your network. This can be done via the ICMP ping, TCP port checks, the ARP, SNMP, DNS, FTP, and HTTP protocol checks. These checks allow you to monitor a wide variety of network hosts and devices. The program should notify you when a device or server goes down automatically. Thanks to this fact, you can react to any problem quickly and recover all failures in time.

The monitoring program can help detecting malicious software on computers in time. The administrator can monitor opened TCP ports via the TCP protocol. Having the list of TCP ports that are frequently used by such applications (the lists can be found on the Internet), you can configure several checks to monitor those opened ports. If the application detects any of the specified TCP ports has opened, it should notify you of that. You can also monitor processes running on remote computers and detect danger applications using this way if the program can check remote processes for existence. In this case, you will need to have names of danger processes and configure the monitoring on remote computers. Mobile Game Developer

Using the same process monitoring check, the administrator can control users' activities on the network. He can be notified when they launch certain applications, such as games, media players, etc. during the working hours.

Some network monitors also allow you to monitor the size of files and folders. Sometimes, application logs increase and occupy too much space on the hard drive of a computer or server. The further log file or temporary folder size increasing can eat all the free disk space and block the workstation or server. The file size monitoring allows you to control the specified file or folder size. You will be warned if the file size reaches the specified volume. The free space on your disks can also be monitored.

The most advanced monitoring programs allow you to monitor MAC address changes. This feature can help protecting your network from unauthorized connections and highly recommended for use. Server Administrator

The network monitor should be able to warn an administrator about particular events in different ways. These include: displaying a message, sending an e-mail message, playing a sound, sending SMS to a mobile phone, executing VB and JS scripts. All the monitoring check results can be recorded to the application log for future analyzing.

Moreover, the administrator should be able to configure the network monitoring application to run particular programs in response to monitoring events. The program can run external applications, restart/shut down a service or a remote computer. User Interface Designer

The network monitoring (which includes controlling hosts, searching slow and defective systems, finding bottlenecks) is one of the most important functions of a network administrator. The whole successful operation of a company depends on how this problem is solved. A good network monitoring program can make this process more effective and simpler.

Resolving Windows Home Server 2003 Error - 'Boot Disk Failure'

There are multitude of reasons that can threaten the availability of data on a server. It includes natural disasters, operating system crash, power outage, virus infection, and more. Since servers are usually deployed to fulfill organizational needs, server failure can cease important operations running in a business, including the exchange of data. Server Recovery service comes in place to recover data from such crashed and ceased servers and involves implementing complicated procedures.Server Administrator

We'll now discuss a realistic server failure problem that can occur to Windows Home Server- the home server operating system used for purposes like, remote data access, file sharing, and automated data backups. Consider a server running Windows Home Server 2003 with two more hard drives. One among these hard disks is the operating system hard drive, while the rest ones are being used for data storage.

Suppose you are the server administrator. To add to your surprise, you might suddenly getting complaints that all the networked computers are disconnected from the server for no apparent reason. On analyzing the root of problem on server computer itself, you find the computer being unbootable and giving the below error on screen:

"Boot Disk Failure. Insert System Disk and Press Enter"

Further, when you view the hard disks' status, you find one or more hard disks, including the operating system hard disk, unrecognized. Consequently, all the data stored on the server is unavailable for access.Mobile Application Developer

The same problem might arise on a very complex server system too. To deal with such problems, you should follow the below sequence of steps:

Make sure that your server computer is not trying to boot from an unbootable disk, that might be connected to the computer. If it is, remove the disk.Mobile Game Developer

Ensure that all the hard disks are properly plugged into the computer.
