5.10. Means of interoperability with other network operating systems

Network can be called an OS that interacts with network equipment and provides intercomputer communications. The user interface to the network allows you to share files and peripheral equipment. The Windows NT operating system is able to communicate and exchange data with many existing networks built on the basis of various network support systems. The circumstances that may lead to this need may be: the presence of networks already built on the basis of other operating systems, the resources needed by Windows NT users; creation of new networks based on Wndows NT and other operating systems supporting networks to increase their efficiency.

The interoperability of networks built on Windows NT with other OS networks support is designed to provide the following tools.

1. Open network structure, mechanisms for dynamic loading and unloading of built-in network support for various network components. These mechanisms can be used to load and unload software from other manufacturers, which allows Windows NT to support many different network protocols, network cards and drivers.

2. Compatible with other networks and communicating with them protocols that support Windows NT. The remote access service for data transmission from one local area network to another remote local area network via the Internet applies the following protocols: PPP — a parallel connection protocol over several telephone channels; SLIP - Internet Protocol for Serial Channel; PPTP is a protocol containing an encryption mechanism for the Internet.

3. Network drivers and interfaces. They provide the ability for Windows NT to connect to various types of networks and interact with various types of computing systems.

4. Multi-user remote access service for systems with Windows NT Server and single-user remote access for Windows NT Workstation systems. It provides remote access over the global network to the Windows NT system. Network connections that are based on different operating systems that support networks are able to serve the server of the remote access service. This is done thanks to the ability to broadcast messages from one format to another, as well as the presence of a multi-access router that establishes and disconnects a network connection, remotely printing and transmitting data over the network to a network component that processes resource requests.

5. Ability to run many applications for different operating systems due to the presence in Windows NT of various APIs. The Win-32 I / O API protocol is required when processing I / O requests from a file that are located on a remote machine, etc.

6. Built-in support for various types of file systems (NTFS, FAT, CD-ROM, VFAT, Macintosh), which can convert FAT and HPFS partitions to NTFS partitions, support for NTFS partitions of Macintosh format directories.

7. Supports Windows NT and NetWare shared directory services NTDSmNDS. For example: a secure directory database, distributed architecture, one-time registration in the network, simple administration.

8. The ability to connect to the domains of new users, for example, users of other networks, maintaining the necessary level of system security by establishing trust relationships between domains. These include built-in tools for working with global networks, which are used to connect one local area network to another through a global network.
