Gateway Services for NetWare (GSNW) is a Microsoft tool that allows you to permanently map drives to NetWare volumes that are available to all users on a server.

A gateway works by stripping the incompatible protocol layers of an incoming packet and replacing them with the alternative headers needed for the packet to reach its destination.

Gateway Service for NetWare (GSNW)

A server that has GSNW installed also must have the NWLink protocol loaded. This protocol, which is an IPX/SPX-Compatible Transport, makes it possible for the Windows server to communicate with the NetWare server. If it is not already installed, NWLink will install automatically on the server when you install GSNW.

The main function of NWLink is to act as a transport protocol to route packets through internetworks.

How It Works

To prepare the NetWare server for the gateway, you must create a group and a user account as follows:

-Create a group called Students on the NetWare server, and give it the necessary rights for accessing the resources you want to make available on the server.

-Create a user account on the NetWare server, and give it the necessary rights for accessing the resources you want to make available on the server. Make this user account a member of the Students group.

GSNW will use this user account for creating a connection to the NetWare server. The connection will appear on the server running Windows NT or Windows 2000 as a redirected drive that can be shared, as if it were a resource located on the Windows-based server. Windows clients can then connect to the shared resource by browsing Network Neighborhood, by mapping a drive using Windows Explorer, or by using the net use command.

From the perspective of the Windows clients on the network, the shared resources they access appear to reside on the Windows-based server. In actuality, the GSNW service on the server is performing protocol conversion between the Server Message Block (SMB) protocol, which the Windows clients understand, and the NetWare Core Protocol (NCP), which the NetWare file server uses.

Advantages of Gateway Services for NetWare

-Seamless access to NetWare data for your users.

-Users do not need NetWare accounts.-No account password synchronization issues.-You can configure different permissions on

the gateway, so that only some users are permitted to access it. This is similar to setting NTFS permissions on a local drive.

Disadvantages of Gateway Services for NetWare

- The performance of GSNW is less than stellar.

- From the NetWare standpoint, all users access the gateway share via the same account.

- A server list is only obtained from the first NetWare server that GSNW attaches to, requiring proper SAP routing in your NetWare environment to access all NetWare servers.

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.

It supports both Bindery (database that contains definitions for entities such as users, groups, and workgroups) and NDS.

Client Service For Networks

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

Advantages-Client Service for NetWare allows for user-level security -Client Service for NetWare allows you to establish user-level

security rather than share-level security. With Client Service for NetWare, you can allow users access to individual user home directories (directories where individual user data resides) that are stored on a NetWare volume. Users can then map to their home directory plus any additional volumes to which they have been granted user-level security. On the other hand, to allow users access to individual home directories with Gateway Service for NetWare, you would need to give each user a separate drive letter.

-Client Service for NetWare might perform better than Gateway Service Client Service for NetWare communicates directly with NetWare servers, avoiding the potential bottleneck caused by excessive traffic moving through a single network connection.

Disadvantages-Client Service for NetWare requires you to

manage multiple user accounts for each user.

-Client Service for NetWare requires more installation and management overhead.

- Client Service for NetWare requires you to add IPX to your entire network.
