Managing SNAplus2 Clients
Managing Win32 Clients
Managing Win32 Clients
For Windows SNAplus2 enables machines running Microsoft Windows 95 and
Windows NT to act as clients in the SNAplus2 domain. The SNAplus2
client software includes API libraries that are fully compatible with
Microsoft SNA Server and the Windows Open Systems Architecture
(WOSA), enabling applications written for SNA Server to run unchanged
on the SNAplus2 Win32 client.
SNAplus2 supports the following WOSA APIs:
• Windows APPC
• Windows CPI-C
• Windows LUA
• Windows CSV
• 3270 Emulator Interface Specification
For more information about Windows SNA APIs, see the documentation
provided with Microsoft SNA Server.
SNA network information, and other information required by Win32
clients, is held in the Windows Program Registry.
On a Win32 client, the component that handles access to SNAplus2
servers is called the Win32 client. The client must be enabled before you
can use SNAplus2 applications or emulation programs on the client. For
more information, see “Enabling a Win32 Client”.
When the client is enabled, it contacts a server running SNAplus2 over
the TCP/IP network in order to access SNAplus2 features. You can
optionally set up SNAplus2 servers to enforce password checking for
Win32 clients when running on Windows 95, so that the client user must
enter the correct password when enabling the client in order to gain
access to the server. For more information, see “Win32 Client Security”.
The operation of the client is also controlled by the information in the
Windows Program Registry. The Windows Program Registry contains
information about the following:
• Configuration information specific to Win32 clients
• Servers that the client can access
