SUMMARY
=======

It is possible to use the SNA Server Clients in MS-DOS and Windows 3.x with
Network Client 3.0 for MS-DOS. However, there are some limitations that affects
the SNA Server Client installation and configuration.


NOTE: The Network Client 3.0 files are located in the \Clients\MSClient directory
on the Windows NT Server compact disc.

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

The following limitations exist when you use the SNA Server Client in MS- DOS
and Windows 3.x with Network Client 3.0:

 - The SNA Server Client does not work if you install the IPX/SPX Compatible
   Transport (NWLink) protocol in Network Client 3.0.

 - When you install the SNA Server Windows 3.x Client on a Network Client 3.0
   network operating system, the following error message appears:

   No Windows network Installed

   The SNA Server Client Setup looks for the LANMAN.INI and the NETAPI.DLL files
   when you use a DOS LAN Manager client. However, these two files do not exist
   for Network Client 3.0. To work around this problem, you must copy the
   NETAPI.DLL file from a DOS LAN Manager client installation to the Network
   Client 3.0 directory (usually C:\NET). For additional information on how the
   SNA Server Client determines the network operating system, please see the
   following article in the Microsoft Knowledge Base:

   Q128118 SNA Server Win3.x Client Setup Err Msg: No Windows network...

 - The SNA Server Client communicates with the SNA Server using named pipes if
   you select Microsoft Networking as the Client/Server Protocol during Setup.
   However, Network Client 3.0 does not support asynchronous named pipes when
   the Client is running under Enhanced Mode Windows. Therefore, you must run
   Windows in standard mode if you want to communicate with the SNA Server. If
   you run Windows in enhanced mode and start the SNA Server Client, the
   following error message appears:

   SNA Server Error: 546
   Cannot establish connection with SNA Server.

 - Network Client 3.0 supports the TCP/IP protocol. Both Network Client and SNA
   Server Client are Winsock compliant. To enable Sockets in Network Client 3.0,
   please see the following articles in the Microsoft Knowledge Base:

   Q128751 No "Advanced" button in Client TCP/IP Configuration Box

   Q142062 Unable to Run Win16 Sockets Application under Windows 3.1

   After you enable Sockets, you can configure the SNA Server Client to use
   TCP/IP as the Client/Server Protocol. This allows you to communicate with the
   SNA Server using TCP/IP Sockets instead of name pipes. As a result, you can
   run Windows in enhanced mode. You must configure the SNA Server Client as
   Remote even though you are logging on to the same domain as the SNA Server.
   The IP addresses of the SNA Server is required in the Primary and Backup
   Server fields. If you enter the name of the SNA Server in these fields, SNA
   Server Error 546 appears. If you configure the Client as Local, SNA Server
   Errors 546 and 629 appear.

As an alternative, you can use the DOS LAN Manager client. The limitations listed
above do not apply to the DOS LAN Manager client. The Setup files for the DOS
LAN Manager client is located in the \Clients\Lanman directory on the Windows NT
Server compact disc.
