Issue:
When you connect to the File Transfer Protocol (FTP) service that is running on your Microsoft Internet Information Services (IIS) server, the FTP service always responds with the following default FTP banner:
220 Microsoft FTP Service
For added security you may not want the FTP service to respond with the manufacture’s name.
Solution:
For Windows 2003 do the following
1) Install the IIS FTP Service
2) Install all the latest Service Packs and Security Updates
3) Run the following command
cscript adsutil.vbs set msftpsvc/###/SuppressDefaultFTPBanner 1
Where ### is the FTP Site number found in the IIS MMC
4) Stop and Start the FTP Site
