systems, and also utilizes recent AS/400 advancements such as NetServer to provide PC
users network print and file serving capabilities. Some highlights of the Express client content
are:
• Runs on PCs having Microsoft Windows 2000, NT 4.0 (Workstation or Server), 98, 95,
and Terminal Server Edition (TSE) operating systems installed. See Informational
APAR II11853 on the Client Access Web page for details on Windows 2000 support.
• Supports TCP/IP connectivity
• Provides enhanced network security through Secure Sockets Layer (SSL) for client
functions
• Uses AS/400 NetServer for PC file serving and network print support
• Contains 32-bit client/server application enablers for AS/400 (such as OLE DB
provider, ODBC driver, ActiveX Automation Objects, Remote Command, and Data
Queues)
• Delivers GUI for OS/400 V4R4 functions through its Operations Navigator function
• Improves administration of PC users from a central AS/400 through improvements to
Microsoft System Policy support and Operations Navigator Application Administration
• Can be used to connect to AS/400 systems using OS/400 V4R2 or later
Customers are beginning to take a closer look at PC alternatives that are easy to administer
centrally (such as something that can be downloaded into a browser or JVM at each use), but
can be maintained on the AS/400 system. Client Access Express has central administration
built into its design. When customers installed the previous Client Access clients, they
typically did this by getting the Client Access PC CD-ROM (or creating diskettes), going to
each PC, and installing the client code. Since the Express client exploits the capabilities of
the AS/400 NetServer, any PC running TCP/IP can directly connect to the AS/400 NetServer
folder where the Express client is installed and start the installation or migration from there.
Furthermore, by combining the use of Client Access options (such as, Silent Install,
CWBBACK, CWBREST), AS/400 administrators can set up the Express client, selecting only
those functions they want their users to have. Then users simply make a TCP/IP connection
to the AS/400 system, start a command, and instal the Express client on their PCs. Once
Express is installed on a PC, it periodically checks the AS/400 system to see if newer code
(service packs or new releases) is in the Express NetServer folder. If it is there, it
automatically updates the end user’s PC. Although Client Access still ships a PC CD-ROM
with the family, you have little use for it when installing the Express client.
The Express client has evolved from the AS/400 Client Access for Windows 95/NT client. A
built-in Migration Wizard makes it easy to replace the Windows 95/NT client with the Express
client. The following sections describe the additional capabilities the Express client provides
to desktop users.
