Interoperability
Windows 2000 Server can coexist with your current environment, whether it is an earlier version of Windows (Microsoft® Windows® 3.x, Windows 95, Windows 98, Windows NT Workstation 4.0, or Windows NT Server 4.0) or a third-party environment such as UNIX, IBM mainframe, or Macintosh. UNIX interoperability is provided through an add-on pack called Windows Services for UNIX. The add-on pack provides support for Network File System (NFS), password synchronization, a UNIX command shell, and a collection of UNIX tools. The add-on pack also supports Network Information Service (NIS). Telnet services (for remote access and administration) are included in Windows 2000 as well as in the add-on pack. Macintosh interoperability is provided by File Server for Macintosh, which allows Macintosh clients to use TCP/IP (AFP over IP) to share files and to access shares on a Windows 2000–based Server computer.
NetWare Interoperability
Windows 2000 Professional uses Client Service for NetWare and the NWLink protocol to provide connectivity between Windows 2000 Professional and servers running Novell Directory Services (NDS) or NetWare bindery-based servers. NWLink is the Microsoft equivalent to the IPX/SPX protocol. On computers running Windows 95, Windows 98, or Windows NT 4.0 Workstation, it is necessary to remove Novell Client 32 before upgrading the operating system, and then reinstall and reconfigure the computer after the upgrade. When using Windows 2000 Professional, you can leave Novell Client 32 on the operating system while upgrading from Windows 95, Windows 98, or Windows NT Workstation 4.0. Windows 2000 Professional upgrades computers running versions of Novell Client 32 earlier than version 4.7. During the upgrade to Windows 2000 Professional, Novell Client 32 version 4.51 is installed. This process allows for a seamless upgrade of Novell Client 32 with no loss in functionality.
UNIX Interoperability
Microsoft® Windows® Services for UNIX 2.0 provides a set of additional features to Windows NT 4.0 and Windows 2000 that allows for greater interoperability with existing UNIX servers in the enterprise. Services for UNIX 2.0 provides fully supported and fully integrated interoperability components that allow customers to integrate Windows NT 4.0 and Windows 2000 operating systems into their existing UNIX environments. It also provides manageability components that enable customer organizations to simplify network administration and account management across both platforms.The add-on pack Services for UNIX version 2.0 adds to Services for UNIX version 1.0 the following new capabilities: Two-way password synchronization between Windows NT 4.0 and UNIX. Administration of Services for UNIX through Microsoft Management Console (MMC). Gateway for NFS allows client computers running Windows 95, Windows 98, Windows NT Workstation, or Windows 2000 Professional access to NFS shared files. Network File System (NFS) version 3.0 support. Network Information Service (NIS) support. Additional UNIX tools support. Migration wizard to migrate NIS source files to Active Directory™ directory service on a Windows 2000–based server configured as a domain controller. Username Mapping Server. ActiveState Perl Engine.
Interoperability with IBM Host Systems
You can integrate the management and troubleshooting of Windows 2000 Professional with IBM host systems by using Windows 2000 Professional with Microsoft SNA Server to directly access IBM host systems. Microsoft SNA Server is Microsoft's solution to integrating personal computer-based clients and servers with IBM host systems. It is also possible to directly connect to an IBM host system without using a gateway like Microsoft SNA Server. This requires the IBM host to support and be configured for either TN3270 or TN5250 telnet access, and then to use host-emulation software that supports direct connection without going through a gateway.For more information about interoperability between Windows 2000 Professional and IBM host systems, see "Interoperability with IBM Host Systems" in this book.
