We strongly recommend that all users upgrade to Microsoft Internet Information Services (IIS) version 6.0 running on Microsoft Windows Server 2003. IIS 6.0 significantly increases Web infrastructure security. For more information about IIS security-related topics, visit the following Microsoft Web site:

SYMPTOMS
When you connect to an Internet Information Server FTP server using Internet Explorer version 1.5, the following error message appears:

This FTP server does not support passive mode.

The attempt to load 'ftp:// ' failed.

Other Web browsers may also fail. Some of the other browsers' error messages are listed below:

Netscape: Netscape is unable to find the file /

Internet Explorer 2.0 for Windows 95: Unable to open ftp://ftpservername



CAUSE
Directory annotation is enabled on the FTP server and the annotation file contains more than 1 line of text.



WORKAROUND
Reduce the annotation text file to one line of text or disable directory annotations. For additional information, please see the following article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed this to be a problem in Internet Information Server version 1.0 and Microsoft Internet Explorer 1.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
