Visual InterDev

When verifying links, Link View frequently interacts with WinInet.dll, the same DLL that Microsoft® Internet Explorer uses for Internet access. If WinInet.dll cannot retrieve a URL, it reports an error. The error may indicate that a server could not be accessed, header information for a page could not be located, and so on.

In Link View, this WinInet.dll error code appears in the ToolTip of the item that could not be located. You can use this error code to help you fix broken links.

The following table lists the more common WinInet error codes and their corresponding error messages and descriptions.
