FP: TCP/IP Test Fails But Other Internet Programs Run (157147)

SYMPTOMS

When you run the Network Test (FrontPage 97) or the TCP/IP Test (FrontPage 1.1), "No" is returned on one or more tests even though other Internet applications run without error. The FrontPage 1.0 TCP/IP Test returns:

"Fail" under similar circumstances.

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.

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.
