Remote Help Desk Jobs Characteristics

A corporate network operating system must support more complex services. Like the network operating system of working groups, an enterprise-wide network operating system should allow users to share files, applications, and printers, and this should be done for more users and data volume and with higher productivity. In addition, an enterprise-wide network OS provides the ability to connect heterogeneous systems - both workstations and servers. For example, even if the OS runs on the Intel platform, it must support UNIX workstations running on RISC platforms. Similarly, a server OS running on a RISC computer must support DOS, Windows, and OS / 2. An enterprise-wide network OS must support multiple protocol stacks (such as TCP / IP, IPX / SPX, NetBIOS, DECnet, and OSI),

An important element of an enterprise-wide network OS is a centralized help desk, which stores information about users and shared network resources. Such a service, also called a directory service, provides a single logical user login to the network and provides him with convenient means of viewing all the resources available to him. The administrator, if there is a centralized help desk on the network, is relieved of the need to have a repeating list of users on each server, which means he is relieved of a lot of routine work and potential errors when determining the composition of users and their rights on each server.

An important property of the remote help desk jobs is its scalability, which is ensured by the distribution of the database of users and resources.

Network operating systems such as Banyan Vines, Novell NetWare 4.x, IBM LAN Server, Sun NFS, Microsoft LAN Manager and Windows NT Server can serve as the enterprise operating system, while NetWare 3.x, Personal Ware, Artisoft LANtastic is more suitable for small workgroups.

The criteria for choosing an enterprise-wide operating system are the following characteristics:

• Organic multi-server network support;
• High efficiency file operations;
• The ability to effectively integrate with other operating systems;
• Availability of a centralized scalable help desk;
• Good development prospects;
• Effective work of remote users;
• A variety of services: file service, print service, data security and fault tolerance, data archiving, messaging service, a variety of databases and others;
• A variety of hardware and software host platforms: IBM SNA, DEC NSA, UNIX;
• A variety of transport protocols: TCP / IP, IPX / SPX, NetBIOS, AppleTalk;
• Support for diverse end-user operating systems: DOS, UNIX, OS / 2, Mac;
• Support for network equipment standards Ethernet, Token Ring, FDDI, ARCnet;
• The presence of popular application interfaces and call mechanisms for remote RPC procedures;
• Ability to interact with the network monitoring and control system, support for SNMP network management standards.
