Client Service for NetWare uses a subset of Gateway Service for NetWare code. You install it on Windows 2000 clients so that they can access NetWare services directly. Unlike Gateway Service for NetWare, clients using Client Service for NetWare do not use the Windows 2000 Gateway to translate CIFS protocol to NCP protocol.
Instead, a Windows 2000 Professional computer running Client Service for NetWare creates NCP protocol packets and passes them directly to the network, as shown in Figure 12.11. The packet is then picked up by the NetWare server.
Figure 12.11 Client Service for NetWare Access
When a drive is mapped to a NetWare volume, the computer running Windows Professional uses a NetWare account to create a validated connection to the NetWare server. This connection appears on the computer running Windows 2000 Professional as a redirected drive.
For example, suppose you want to create a connection from computer A (running Client Service for NetWare) to the NetWare \\B\Server1\Org_Unit.Org\Data volume on the NetWare NDS-based server B. You would simply create the connection by using Map Network drive or the net use command-line utility and specifying the path \\B\Server1\Org_Unit.Org\Data for the NetWare resource. For information about mapping drives, see the Windows 2000 Professional Help.
After the mapped connection is established, it is disconnected only if a network problem prevents access to the NetWare server, if the drive is manually disconnected, or if the computer running Windows 2000 Professional is turned off. The mapped drive is then reestablished when the user logs on to the network.
Note
Because requests from Windows Professional client using Client Service for NetWare are processed through a dedicated single connection to the NetWare server, access is faster than with shared access through a Gateway Service for NetWare gateway. For more information about deciding between Gateway Service for NetWare and Client Service for NetWare, see "Choosing Between Gateway Service and Client Service" earlier in this chapter.
Packets are redirected to NetWare file and print servers through Client Service for NetWare similarly to Gateway Service for NetWare, except that they are executed on the Windows 2000–based client. As Figure 12.12 shows, the packets pass through Io.sys, then through the Nwrdr.sys redirector, and then they are transmitted onto the LAN using the NCP protocol.
