Microsoft FTP Service 7.5 for IIS 7.0 is a completely rewritten, robust File Transfer Protocol server engine designed by Microsoft for Windows Server 2008 environments. Unlike the legacy IIS 6.0-based FTP engine that originally shipped on the Windows Server 2008 media, FTP 7.5 was released out-of-band (as a separate download) specifically to introduce modern internet standards, tighter security, and unified administration to IIS 7.0. Key Features and Capabilities
Tight IIS 7.0 Integration: The engine completely abandons the old IIS 6.0 metabase. It integrates directly into the modern .NET XML-based applicationHost.config store and plugs seamlessly into the updated IIS Manager interface.
Unified Web/FTP Publishing: Administrators can bind both HTTP/HTTPS and FTP protocols to the exact same web site container. This allows web authors to seamlessly manage and publish content to a single directory using different protocols.
FTP over SSL (FTPS): It introduces native support for secure data transmission by allowing the binding of SSL/TLS certificates directly to the FTP traffic.
Virtual Host Name Support: Similar to HTTP host headers, this version allows hosting multiple distinct FTP sites using a single shared IP address, which is highly beneficial for shared hosting environments.
Advanced Authentication Providers: Beyond standard Windows local or Active Directory accounts, FTP 7.5 natively supports custom non-Windows authentication schemas like IIS Manager Accounts and .NET Membership providers.
Enhanced User Isolation: It allows strict file mapping so that users can be restricted and isolated within their own per-user virtual directories, preventing them from accessing or seeing other users’ data.
Modern Standard Protocols: Adds robust, native support for IPv6 routing and UTF-8 encoding for international character sets.
Deeper Logging & Diagnostic Support: Enhances tracking by logging unique FTP sessions, sub-statuses, and all traffic details while integrating with Event Tracing for Windows (ETW) for granular troubleshooting. Installation and OS Scope
Windows Server 2008 (IIS 7.0): Must be downloaded manually as an extension. It is available via separate x86 and x64 installer packages.
Windows Server 2008 R2 / Windows 7 (IIS 7.5): You do not need to download this package. FTP 7.5 ships natively built-in as an optional feature of the server role inside those operating systems.
