NOTE: RTM has been released see the following blog: http://blogs.msdn.com/carlosag/archive/2008/03/04/IISManagerForWindowsXPand2003andVista.aspx 

With the release of Windows Server 2008 RC0, in IIS we are also releasing the ability to manage the Web Server, the new FTP Server and the new modules remotely using IIS Manager 7.0.

In the past with previous Beta we shipped similar functionality under a different name, however for the first time this is the real way we will be supporting this remote administration from different Windows versions when Windows Server 2008 final version comes along.

The reason this release in particular is exiting is because for the first time all the UI extensibility is enabled for these platforms making it possible to build your own UI modules, install them in the server and have the clients that connect to your server automatically download the new functionality and use it as it was part of the IIS Manager release.

Another reason this is important for us is because this is the first time we are releasing support for x64 which is something required for customers using Windows Vista 64 bit edition or any other 64 bit version of Windows.

You can download and install them from:

x86

x64

Note: This RC0 version will not be able to connect to any other older build of Windows 2008 Server including Beta 3, so if you need to still manage Beta 3 version you will need to install the Beta 3 build of the tool which can safely live side-by-side with the RC0 build.
