When using any TCP/IP application, such as an email reader, web browser, telnet client or Secure Shell client, it is possible for numerous errors in both configuration and networking, to occur.
Many applications do not report these errors, but simply tell you that you have a network error. Our products are designed to try to provide you with as much information as possible. We feel it is better to display this to the user than to hide it from them as it will help diagnose what may be going on.
Below is a list of possible errors, as reported by Microsoft. If we do not know it (or it is quite rare), we will report it to the user and you can look it up below. If you do not find the error here, check the Microsoft MSDN web site at
