SYMPTOMS
When you try to open a document on a secured FTP server in Microsoft Windows XP, you receive an error message. The error message states that the document cannot be opened.

Note A secured FTP server does not accept anonymous requests. To access a file on a secured FTP server, the user name and password must be supplied as a part of the URL that is used to make the request. This URL uses the following format:

ftp:// : @ /

CAUSE
The problem occurs because the document is removed from the cache before the application can open the document. The document is removed because of special handling that is used when you access secured documents by using an authenticated FTP URL. The problem is known to occur when you use the .tif, .doc, or .xls document extensions. However, the problem may also occur when you use documents that have different extensions.



RESOLUTION

Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

Double-click the FEATURE_PERMIT_CACHE_FOR_AUTHENTICATED_FTP_KB910274 subkey.
