I know this is a lot of information to read and understand. Think of it as an investment and not a burden. I have tried to include what is necessary without writing a whole book about a 5 minute procedure. Summary of steps to install a network printer. 1. Download the most recent driver from the manufacturer's website. 2. Configure network settings on the printer. 3. Use the Add Printer Wizard to create a local network printer on the pc. 4. (Optional) - share printer to other users. If you are performing this type of installation for more than a handful of people, it is best to install this once on a Windows Server and share that printer to everyone. Normally it takes between 5 and 10 minutes to perform this type of install on each pc. 1. Download the most recent driver. Visit the manufacturer's website to obtain the latest driver - print drivers can be found in the support area searching by model number. ( this is important because early problems are fixed and drivers are upda...

Troubleshooting computer network is among the most important job descriptions of the network administrators, system administrators, network technicians and the IT consultants. A computer network can have different kinds of problems such as it can be infected with virus and spyware, attacked by hackers, accessed by unauthorized users and may face connectivity failure issues due to the faulty network devices or configurations. Following is a list of the basic network troubleshooting commands that are built-in the Windows based operating systems and UNIX etc. The right use of these troubleshooting commands can helps a lot in diagnosing and resolving the issues with your computer network. PING Ping is the most important troubleshooting command and it checks the connectivity with the other computers. For example your system’s IP address is 10.10.10.10 and your network servers’ IP address is 10.10.10.1 and you can check the connectivity with the server by using the Ping command in following ...

TCP/IP provides a total of 65,535 ports of which 1023 are considered to be well known ports. In reality the number of ports that are used by popular network clients and services comprises an even smaller subset of the well known group of ports. The following table lists the functions of this subset. Port Assigment Description 20 FTP File Transfer Protocol (Data) - The File Transfer protocol provides a mechanism for transferring specific files between network connected computer systems (usually a Linux or UNIX based system). Transfer is typically performed using the ftp client which provides a range of commands used to connect to a remote server for the purpose of uploading or downloading files. Most modern web browsers also have the ability to browse and download files located on a remote FTP server. FTP uses TCP (rather than UDP) to transfer files so is considered to be a highly reliable transport mechanism. FTP does not encrypt data and is not considered to be a secure file ...
