On a computer that is running Windows 2000 or Windows XP, the FTP service is installed in Internet Information Services (IIS) 5.0 or IIS 5.1. You apply security update 975254 on this FTP server. In this situation, you may experience the following issues when you use an FTP client to connect to an FTP site that is located on this FTP server.
Issue 1After the FTP client sends a QUIT command to the FTP service, the FTP service adds some additional characters to the response unexpectedly. For example, the FTP service typically sends the response "221" after it receives a QUIT command. However, the response contains the additional characters ".Bs.". This may cause the FTP client to function incorrectly.
Issue 2The IIS FTP service is configured to display UNIX-style directory listings. When you send an FTP DIR command to the FTP service by using the FTP client, permission information is not displayed in the response.
For example, a line of dashes are displayed instead of permission information:
ftp> dir 200 PORT command successful. 150 Opening ASCII mode data connection for /bin/ls. ---------- 1 owner group 5 Oct 27 17:42 A.MIN
