Resolution

To resolve this problem, obtain the latest service pack for Microsoft Internet Explorer 6.0. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

After you apply the fix, you must make sure that the Web server that you download the PDF file from sends "Accept-Ranges: bytes" in the HTTP Response Header. However, this problem still occurs when the header is sent if the PDF file is less than 8 KB.

To work around the problem in this case and send the header, pad the PDF file so that its size is greater than or equal to 8 KB.
