SUPPORT SOLUTION:
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 1
2, ’symptoms’);
After 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 2

The 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.
