======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft SNA Server, versions 3.0, 3.0SP1, 3.0SP2, 3.0SP3, 4.0, 4.0SP1 
-------------------------------------------------------------------------------

SYMPTOMS
========

SNA Server does not allow workstations to be defined using the workstation's
media access control (MAC) address, except in the case of Internetwork Packet
Exchange (IPX) clients. IPX addresses include the MAC address of the
workstation; therefore they are identified by their MAC addresses. Workstations
cannot be defined using their MAC addresses if they communicate with the SNA
Server using TCP/IP.

CAUSE
=====

SNA Server was not designed to allow the use of MAC addresses for workstation
definitions for TCP/IP connected clients. SNA Server does not know the MAC
address of TCP/IP connected clients, because this information is not returned to
the SNA Server computer by the SNA Server client software.

STATUS
======

Microsoft has confirmed this to be a problem in SNA Server versions 3.0, 3.0
SP1, 3.0 SP2, 3.0 SP3, 4.0, and 4.0 SP1.

This problem was corrected in SNA Server version 4.0 U.S. Service Pack.

MORE INFORMATION
================

With these updates applied, SNA Server 4.0 SP1 allows you to define workstations
using the client's MAC address to connect to SNA Server with TCP/IP.

NOTE: Updates must be made to both the SNA Server computer and all Windows 95 and
Windows NT clients to support this new feature. TCP/IP clients that do not have
the updates applied continue to function correctly, but LUs/Pools cannot be
assigned to their MAC addresses.

After you apply the updates, to define workstations using a MAC address: in SNA
Server Manager, in the Workstation Properties dialog box, in the Workstation ID
box, type the MAC address. In addition, ensure the Workstation ID Type parameter
is set to Address.

There are three ways you can add a TCP/IP connected workstation to the SNA Server
configuration file:

+--------------------------------------+
| Workstation ID | Workstation ID Type | 
+--------------------------------------+
| NetBIOS name   | Name                | 
+--------------------------------------+
| TCP/IP address | Address             | 
+--------------------------------------+
|                |                     | 
+--------------------------------------+
| MAC address    | Address             | 
+--------------------------------------+

When SNABASE searches for the user's workstation definition in the configuration
file, it does so in the order shown above (that is, a workstation name has the
highest priority, next highest priority is the TCP/IP address, and lowest is the
MAC address). The rights do NOT accumulate. For example, if both a NetBIOS name
and a TCP/IP address are configured for the same workstation, the TCP/IP address
is never used (assuming the workstation has a NetBIOS name).

NOTE: The new feature requires that you install Client for Microsoft Networks on
the Windows 95 system that runs the SNA Server client for Windows 95.
