Configuring The Network Server

- 2. © Koffi N’Da, Server Hardware Component Client Server Processor 486 or greater Pentium or RISC-based Display VGA or better VGA or better Hard disk space About 50MB plus the storage space for a single user and application About 90MB (110 for RISC) plus storage space for a single user and applications Memory At least 8 MB At least 16 MB
- 3. © Koffi N’Da, The Network Operating System (NOS) Windows, Unix, DOS, OS/2 A complete network requires two type of network software The network operating system, which runs on server and allows you to share server resources such as hard disk space, printer, and CD-ROMs. Client network access software, which runs on the client and provides access to the resources shared by the server.
- 4. © Koffi N’Da, Client Software The purpose of client software is to make the services that are available on the network appear to be local to the client computer. This way application software can be written without regards to where printers, hard drives, and so on are located.
- 5. © Koffi N’Da, Server Software Servers are the waiters of the network world- they exist simply to listen for and satisfy the requirements of clients. Servers provides following services: Managing user accounts Security Central licensing Data protection: Archiving, Fault-tolerant file system, Uninterruptible power supplies, Replication Multitasking and Multiprocessing
- 6. © Koffi N’Da, Windows NT Server Installation You should prepare or determine several things in advance to make the installation process go smoothly: Hardware Compatibility List (HCL) Server naming information Server responsibilities (PDC, BDC) Hard drive partitioning Network adopter card setting TCP/IP installation information
- 7. © Koffi N’Da, Windows NT Server Installation The operating system installation process is not the same every time but it varies, depending on the following: The CPU(s) and memory in the server computer The number and partitioning of the hard drives in the computer. The jobs of the server will perform on the network Whether the software is being installed for the first time or being upgraded. The hardware devices and adopter cards installed in the computer. The size and type of network on which the server will be installed. The type of files system(s) the server will use.

- 10. © Koffi N’Da, Network Applications E – Mail Server: E – Mail Servers store and transfer messages on the network. Think E-Mail Servers as post offices of e-mail. For transfer and receiving the messages two important protocol are mostly used i.e. Post Office Protocol (POP) and Simple Mail Transport Protocol (SMTP)
- 11. © Koffi N’Da, E – Mail Protocols POP and SMTP: Internet mail uses the Post Office Protocol (POP), which describes how e-mail clients interact with e-mail servers, and Simple Transport Protocol (SMTP), which describe how e-mail servers transfer e-mail messages to their intended recipients. X.400 and X.500: Some cross platform e-mail systems use the ITU formerly CCITT. X.400 messaging protocol, and X.500 directory services protocol to implement mail standards. MHS: Message Handling Services (MHS) is the Novel Netware e-mail standard. It similar to X.400. MAPI: Message Application Programming Interface (MAPI) is the Microsoft standard for messaging in Microsoft networks and is the internal Mil standard used by Exchange

- 13. © Koffi N’Da, Network Applications Shared Network Applications Stand alone application: 1. Lower licensing costs. 2. Version control: When one copy of the application resides on the server, you can be sure everyone is using the same version of the software. 3. Administration: It is easier to install the software once on the server than once each for every client on the network. Network aware application: 1. Locking files so only one user at a time may modify them. 2. Providing for security at the application level so you can give users different levels of access. 3. Connecting to e-mail services to exchange application data among users
