I was evaluating the much anticipated Windows Server 2008 RC1 and one of the areas I was focusing on was IIS7. Pretty much every component was updated except for the FTP server. It seems that Microsoft was rushing RC1 out and didn't have enough time to add the new FTP server in there so they went with the old version instead.
When you enable FTP role, the old IIS 6 snapin will be added to let you manage the FTP server. I didn't like the way it turned out and searched around a bit more and found out FTP Server 7 RC0 is out.
You can download the new FTP Server here. In order to install this package, you must first uninstall the old FTP version.
