What is Client Services for NetWare?

Client Services for NetWare, also known as CSNW, is a service that can be installed on Microsoft Windows NT Workstation computers to enable them to directly connect to file and print resources on Novell NetWare servers. In other words, Client Services for NetWare (CSNW) is Microsoft’s version of the NetWare redirector for Windows NT. Microsoft Windows 2000 Professional also has a similar service with the same name.

How it works

CSNW is a full-featured, 32-bit client for NetWare networks that can be installed on Windows NT Workstation by using the Services tab of the Network utility in Control Panel (or on Windows 2000 Professional by using the Network and Dial-up Connections utility in Control Panel). If you are connecting to a NetWare 3.12 or earlier server, you must specify a preferred NetWare server for access to its bindery. If you are connecting to NetWare 4, specify the Novell Directory Services (NDS) tree and default context. CSNW supports browsing NDS trees, but does not support administration of NDS trees.

Additional options are included for printing and login script support. CSNW requires installation of the NWLink IPX/SPX-Compatible Transport protocol, but if it is not installed already, it will be added automatically when you install CSNW on a machine.

CSNW connections to servers

CSNW supports connections to servers running version 2, 3, or 4 of NetWare, including both bindery emulation and NDS on NetWare 4. CSNW includes support for

  • NetWare Core Protocol (NCP)
  • Large Internet Protocol (LIP)
  • Long filenames (LFNs)

NetWare connectivity on Windows 2000 and NT Server

On a machine running Windows NT Server or Windows 2000 Server, NetWare connectivity is provided by Gateway Services for NetWare (GSNW). Use CSNW to provide your Windows NT Workstation clients with dedicated access to Novell NetWare servers; use GSNW only to provide occasional access to NetWare servers from Windows NT Workstation or Windows 2000 Professional clients.
