Many still use SQL Server/Reporting Services 2005 although sometimes alread on Windows Server 2008 / Vista / Windows 7.

I absolutely do recommend upgrading to SQL Server 2008. There are many advantages in the combination - be it security or performance (Security, Performance, No need for IIS) - but if you can't uprade right now, you do need to install IIS for Reporting Services 2005 to run.

I have seen recommendations (even on a Microsoft blog) where they tell you to install EVERY Role Service for IIS - but that is untrue and against basic security principles.

I always always recommend "install as little as possible, but just as much as required".

You do not need an FTP-Server to run Reporting Services! - Natural to most. But when it comes to less known features like, CGI , SSI, Tracing..?.. most aren't so sure.

So here is the definite list of required role services for IIS. I tried to leave of everything I could, and this turned out:

I also attach a cmd-file. This file will install all the required packages by itself. You do not need to don any IIS Installation beforehand. It's using the new Package Manager available on Windows Server 2008. Just remove the .txt after you checked it out ;-

If You are using Windows Server 2008 R2/Windows 7 with IIS 7,5, Package Manager is deprecated. Instead use Deployment Image Servicing and Management as described here: http://blogs.msdn.com/b/habibh/archive/2009/08/14/how-to-install-iis-7-5-on-windows-7-using-the-command-line.aspx

I also prepared a file using DISM, which you can download here.

For Some reason though the Packetmanager installs "Directory Browsing, which is NOT required (bull***) - you should remove it manually. This seems to be a bug with Package Manager.

At the end it should look like this:

 IIS will be properly detected (and we know for sure, that "Directory Browsing" is not a requirement"):

There is still something however:

After you installed and navigate to http://YourServername/Reports

You will get an error: "unable to connect to remote server"

when checking the Logfile  "ReportServerWebApp" it says:

w3wp!ui!7!22.10.2008-10:24:47:: e ERROR: Unable to connect to the remote server
w3wp!ui!7!22.10.2008-10:24:47:: e ERROR: HTTP status code --> 500
-------Details--------
System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:443

Solution:

In IIS 7 Manager, highlight the ReportServer application (Not "Reports")

go to Handler Mappings, click "Edit Feature Permissions" in the "Actions Pane", and enable "Script and Execute".

You are all set - it should be running just fine now.

Everything described here also applies for running Reporting Services 2005 on Windows Vista (SP1).

Download to IIS 7 Setup-File using Package Manager (rename to .cmd or .bat)

Download to IIS 7.5 Setup-File using DISM (rename to .cmd or .bat)

I also found a nice explaination of the IIS-Setup here: http://learn.iis.net/page.aspx/130/understanding-setup-in-iis-7/
