FP98: TCP/IP Test Fails But Other Internet Programs Run (194353)


The information in this article applies to:

  • Microsoft FrontPage 98 for Windows
This article was previously published under Q194353

For a Microsoft FrontPage 2000 version of this article, see 205466.
For a Microsoft FrontPage 97 and earlier version of this article, see 157147.

SYMPTOMS

When you run the Network Test, "No" is returned on one or more tests even though other Internet applications run without error.

CAUSE

This problem occurs because FrontPage uses more of the Winsock features than most Internet applications. Unlike most Internet applications, FrontPage not only browses and retrieves files via Winsock, it also requires your computer to act as a Web server.

Not every third party TCP/IP stack includes all of the industry standard Winsock API calls. Therefore, if the TCP/IP test fails, FrontPage will be unable to work with that particular stack.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

When the TCP/IP Test or Network Test begins, it loads the Wsock32.dll and then it looks for clear entry points. If the test does not locate any clear entry points, the test calls the WSAStartup startup routine, which is one of the entry points found, and it requests version 1.1 or higher of the Winsock API.

The TCP/IP test or Network Test then attempts to execute the following Winsock API calls: 
   WSACleanup
   socket
   inet_addr
   inet_ntoa
   bind
   listen
   getsockname
   connect
   accept
   send
   recv
   closesocket
   gethostname
   gethostbyname
FrontPage will work only with third-party TCP/IP stacks that properly support all of these API calls.

Winsock is the common name for the Windows Sockets Interface Specification. This specification defines a network programming interface for Microsoft Windows which is based on the "socket" paradigm popularized in the Berkeley Software Distribution (BSD) from the University of California at Berkeley. It encompasses both Berkeley socket style routines and a set of Windows specific extensions designed to allow a programmer to take advantage of the message-driven nature of Windows.
