# Chapter 1
Introducing the Advanced Server

The Advanced Server is a network operating system (NOS) based on OpenVMS that is fully compatible with Microsoft networking technology.

As a server for workstations on a network, the Advanced Server provides file and print services that enable a community of desktop users to share computing resources efficiently. The Advanced Server can function as a simple file and print server for a small, isolated community of users or as the foundation of a large network distributed over a wide geographical area.

The Advanced Server represents the new generation of LAN Manager systems technology. It enhances the LAN Manager functionality by incorporating the latest Microsoft technology to deliver powerful new features for network administration and enhanced security. The Advanced Server interoperates with systems running Windows NT and Windows 2000 software.

The Advanced Server is based on Windows NT Server source code from Microsoft and AT&T. As a result, the Advanced Server can take advantage of the OpenVMS operating system's native ability to function simultaneously as a file, print, communications, and applications server while ensuring compatibility with Microsoft networking features and interoperability with Microsoft desktop environments. In fact, the Advanced Server provides networking that is functionally equivalent to that of the Windows NT Server. The Advanced Server can operate independently or in cooperation with the Windows NT Server (or with a Windows 2000 server).

The Advanced Server can be remotely administered from PATHWORKS and Microsoft Windows client workstations. These workstations include Windows 3.1, Windows for Workgroups, Windows 95, Windows 98, and Windows NT. Advanced Server can also be managed remotely from Windows NT Servers and other Advanced Servers.

Advanced Server maintains full down-level compatibility with LAN Manager client and server software. LAN Manager users can add an Advanced Server to an existing network and migrate to the new technology at their own pace. A PATHWORKS LAN Manager server can be upgraded to Advanced Server technology or act as a backup domain controller, member server, or standalone server in a network in which the primary domain controller is an Advanced Server or a Windows NT Server computer.

The Advanced Server can be deployed as the primary domain controller in a network comprising other Advanced Servers, Windows NT Servers, PATHWORKS for OpenVMS (LAN Manager) servers, or LAN Manager for OS/2 servers. It also can act as a backup domain controller for other Advanced Servers and Windows NT Server computers. In addition, the Advanced Server can act as a backup domain controller in Windows 2000 mixed-mode domains, or as a member server in native-mode and mixed-mode Windows 2000 domains. Windows 2000 mixed-mode domains contain both Windows 2000 domain controllers and Windows NT or Compaq Advanced Server domain controllers. Windows 2000 native mode domains, also referred to as pure Windows 2000 domains, are those whose domain controllers are Windows 2000 systems exclusively.

Support for WINS (Windows Internet Name Service) integration allows Advanced Server servers to act as WINS clients; that is, to use the name registration and resolution facilities available from a Microsoft WINS server across routed wide area TCP/IP networks, thus enabling WAN support via WINS for domain functions.

Support of LMHOSTS enables the Advanced Server to resolve NetBIOS names by looking them up in a local database that maps NetBIOS names to TCP/IP addresses.

The Advanced Server can also use the name resolution facilities available from a DNS (Domain Name System) server for WAN support.

Note When DNS is configured for use by the Advanced Server, it does not replace WINS or LMHOSTS but rather supplements them. DNS is used primarily for resolving node or computer names; it is not used for resolving domain names. With DNS, the Advanced Server still uses LMHOSTS, WINS, or both methods for resolving domain names and certain other names.

This guide explains the concepts that support the Advanced Server.

Note In this guide, the term "Advanced Server" may be applied to either version of the file and print server: Advanced Server for OpenVMS PATHWORKS for OpenVMS (Advanced Server)

For instructions on installation and initial configuration, see the appropriate Server Installation and Configuration Guide.

For instructions on administrative procedures, see your Server Administrator's Guide.

For descriptions of the syntax of ADMINISTER commands, see the Compaq Advanced Server for OpenVMS Commands Reference Manual or the ADMINISTER online help at the OpenVMS DCL prompt (the Advanced Server must be installed on the OpenVMS system).

The remaining sections of this chapter outline the features provided by Advanced Server.

# 1.1 Platform and Application Independence

The Advanced Server supports the full range of Microsoft desktop environments, allowing network clients to run favorite applications locally and access the Advanced Server's resources transparently through a familiar interface.

Advanced Server for OpenVMS supports connections from the following types of clients:

- Windows NT V4.0
- Windows 95, Windows 98, Windows 2000, and Windows 2000 Professional
- Windows for Workgroups
- PATHWORKS 32

# 1.2 Network Integration Transports and Protocols

Advanced Server accepts connections from systems with the following protocols:

- DECnet (Phase IV)
- DECnet-Plus (formerly known as DECnet/OSI)
- NetBEUI (recommended for use in small LAN-only environments of 50 nodes or less)
- TCP/IP (required for wide area networking)

For more information about network protocols, see your Server Administrator's Guide.

# 1.3 Integration with the OpenVMS System

The Advanced Server encompasses many of the features of the OpenVMS operating system, including OpenVMS Clusters and symmetric multiprocessing. OpenVMS Cluster configurations provide failover and extensive resource capacities by integrating multiple OpenVMS systems that can be accessed using a single cluster name. The Advanced Server provides load balancing of client access requests. (See your Server Administrator's Guide for more information on the load balancing supported by your server.)

The Advanced Server provides an extension to the Windows NT security model by supporting OpenVMS security enforcement as an optional enhancement. In addition, the Advanced Server supports password synchronization between OpenVMS and Advanced Server systems, and it supports user account lockout.

The Advanced Server includes full support for the latest features of OpenVMS, such as:

- Extended File Specifications and ODS-5 (On-Disk Structure 5) disk volumes, providing greater compatibility with the Windows 2000, Windows 98, Windows 95, and Windows NT file systems
- OpenVMS Registry
- OpenVMS infrastructure changes for External Authentication and the distributed common object module (COM for OpenVMS)

# 1.4 Down-Level Interoperability

The Advanced Server interoperates with the installed base of Microsoft server and desktop environments. For example:

- The Advanced Server interoperates with LAN Manager V2.x servers on any platform --- even in the same domain. MS-DOS, OS/2, and Windows 3.1 computers running LAN Manager V2.x client software can access systems running the Advanced Server. See Section 2.5.4, LAN Manager V2.x Servers, for more information.
- The Advanced Server can act as a server for standard MS-DOS client networks, in configurations with or without PATHWORKS client software.
- The Advanced Server supports connectivity with Windows for Workgroups.

# 1.5 Management Interfaces

You can use any of the following interfaces with the Advanced Server:

- Advanced Server ADMINISTER command-line interface --- This command-line interface conforms to standard DCL command syntax. (The ADMINISTER command-line interface also provides automatic translation of Net commands that have ADMINISTER command equivalents.)
- Windows NT server administration tools --- These management tools are included in the Advanced Server software kit for you to install on Windows NT workstations or Windows-based computers. You can use these tools to manage the Advanced Server remotely from your client workstation.
- Windows NT Server tools --- These tools are available as part of the Windows NT Server.
- Windows NT printer management --- The Advanced Server for OpenVMS gives you the option of configuring the server to allow management of shared printers from Windows NT. For more information, see Section 7.4, Managing Print Shares, Print Queues, and Print Jobs.

To administer the Advanced Server from a Windows client workstation, you must install Windows NT server administration tools. This set of tools allows you to administer the Advanced Server and Windows NT Server computers from network clients, such as Windows NT V4.0, Windows 2000, Windows 95, Windows 98, and Windows for Workgroups clients. An installable version of the tools is shared automatically by the Advanced Server. The tools are made available in the PWUTIL share after installation and configuration of the Advanced Server is complete.

See the README.TXT file included with the Advanced Server software for installation instructions for the Windows NT server administration tools. See Appendix A, Differences Between Advanced Server and Windows NT Server, for more information about differences between the two network operating systems.
