I was about to setup FTP Service in my production server which is Window Server 2008 standard edition (x64). I was not able to find FTP publishing service in fresh installation. I did the following steps to install;
Server Manager -> Roles -> Under Roles Services : you can find FTP Publishing Service -> Select and click Add Roles Service to install the feature.
When i did the above steps, after installation to my surprise i found FTP 6 got installed!
FTP Services 7:
Then from forums found Microsoft has written New FTP services (FTP Publishing Service 7) for Windows Server 2008 which could be downloaded from the following links:
Download FTP Publishing Service for Windows Server 2008 (x64)
Download FTP Publishing Service for Windows Server 2008 (x86)
Hope it helps...
