                        Windows NT Workstation and Server Optimized For
                        Different Role

                        The information in this article applies to:
                           o Microsoft Windows NT Workstation version 3.5
                           o Microsoft Windows NT Server version 3.5
                           o Microsoft Windows NT Server version 4.0
                           o Microsoft Windows NT Workstation version 4.0

                        SUMMARY

                        This article discusses the roles for which Windows
                        NT Workstation and Windows NT Server are
                        optimized.

                        MORE INFORMATION

                        Microsoft optimized both Windows NT Workstation
                        and Windows NT Server to better serve their
                        intended purposes. Windows NT Workstation is a
                        great corporate client for users who need the
                        power, scalability, fault tolerance, or security
                        it offers. Windows NT Server is a powerful server
                        environment for customers who want to leverage its
                        application server, file and print services, or
                        remote access capabilities. The following
                        optimizations were made in Windows NT version 3.5:
                           o The write-throttling mechanism (the point at
                             which dirty data is flushed to disk) is
                             implemented differently for the Windows NT
                             Server and Windows NT Workstation. This
                             allows the server to handle server-like loads
                             and the workstation to handle desktop-like
                             tasks.
                           o The internal code that provides the Windows
                             NT Server server functionality (SRV.SYS) is
                             less pagable. This leads to better response
                             times under heavy server-type loads.
                           o Under Windows NT Workstation, the Windows NT
                             Virtual DOS Machine (VDM) is pre-loaded for
                             improved application startup times. Windows
                             NT Server does not pre-load the VDM, but
                             instead optimizes server file operations.
                           o Windows NT Workstation and Windows NT Server
                             use a different number of system worker
                             threads and threads for blocking operations.
                             Windows NT Server is optimized for fast
                             server type I/O operations and Windows NT
                             Workstation is optimized for desktop
                             applications.
                           o Windows NT Server can be optimized for file
                             and print server performance or application
                             server performance, allowing you to tune it
                             for maximum throughput depending on the type
                             of server usage. Windows NT Workstation does
                             not have this feature. Internal testing has
                             also shown that Windows NT Workstation
                             performs about the same as Windows NT Server
                             up to approximately 10 different,
                             simultaneous inbound user connections. This
                             enables Windows NT Workstation to function
                             well in a small peer environment. Windows NT
                             Server is the correct choice if you want to
                             deploy a server in a larger environment or
                             want to scale your network in the future.

                        These optimizations changed the performance of
                        Windows NT Workstation when used as a server. As a
                        result, peer networking is still supported for
                        basic connectivity between users on a network. You
                        can still make unlimited outbound connections to
                        server resources. However, Windows NT Workstation
                        now supports a maximum of 10 simultaneous inbound
                        connections. Our research has shown that systems
                        with this many connections are almost always being
                        used as dedicated file, print and/or application
                        servers.

                        While Windows NT Server can certainly provide
                        excellent file and print services, it can also be
                        used extensively as an application server platform
                        for database and other services. The Windows NT
                        Server file and print capabilities can be
                        selectively implemented.

                        Windows NT Server includes the following
                        capabilities not available on Windows NT
                        Workstation:
                           o Dynamic Host Configuration Protocol (DHCP)
                             server service (Both Windows NT Workstation
                             and Server have DHCP Protocol)
                           o Windows Internet Naming Service (WINS)
                           o Single network logon
                           o Data protection features (disk striping, RAID
                             5, disk mirroring)
                           o Remote Access Server service can handle 255
                             concurrent incoming calls (Windows NT
                             Workstation limited to one incoming call)
                           o Gateway Services for NetWare(GSNW)
                           o Gateway to NetWare file and print resources
                             for MS network clients
                           o Services for Macintosh (allows Macintosh
                             clients to access file and print resources on
                             the Windows NT Server, and allows Microsoft
                             network and Macintosh clients to access
                             AppleTalk-based printers)
                           o Netlogon request authentication (for running
                             logon scripts)
                           o Account lockout security
                           o Network Client Administrator
                           o Administrative tools (Server Manager, User
                             Manager for Domains)
                           o Support for remote boot of diskless
                             workstations (RPL)

                        Because Windows NT Server is optimized as a server
                        platform, it is required to run Microsoft
                        BackOffice products (Systems Management Server,
                        SNA Server, SQL Server, and the upcoming Exchange
                        Server).

                        Microsoft recommends Windows NT Workstation as a
                        desktop operating system and Windows NT Server as
                        a server operating system for server applications.
                        This provides you an environment that is
                        architecturally very clean, since both the desktop
                        and server are running the same operating system,
                        and have the same APIs, etc.
