The information in this article applies to:

- Microsoft Network Client for MS-DOS, version 3.0

SYMPTOMS

You cannot run 16-bit Windows sockets application under Windows 3.1 when using the real mode TCP/IP stack provided by Microsoft Network Client for MS-DOS 3.0. The winsock application fails at startup with an error returned by WSASTARTUP() function. WSASYSNOTREADY or WSANOTINITIALIZED errors may be returned.

CAUSE

When you install the real mode TCP/IP stack , Network Client for MS-DOS Setup does not copy one of the files necessary for Windows Sockets support. The file is WSAHDAPP.EXE. This file is located in the Windows NT Server CD- ROM in uncompressed format in the \CLIENTS\MSCLIENT\NETSETUP directory and in a compressed format in the \CLIENTS\MSCLIENT\DISKS\DISK2 directory.

RESOLUTION

Manually copy WSAHDAPP.EXE from the CD-ROM to the directory where the Network Client for MS-DOS is installed (by default: "C:\NET"). For additional information on configuring Microsoft Network Client for MS-DOS 3.0 for sockets support, please see the following article in the Microsoft Knowledge Base:
