The report manager site not working properly after I install theSQL Server 2005. I have been tried to fix it since yesterday. But it just getting worse. I need to get this to work properly before I can install theVisual Studio Team FoundationServer.

I am following the Visual Studio Team Foundation Installation Guide.
The Steps I have done so far are:

1. InstallSQL Server 2005 and assign application pool to reports and report server sites in IIS.

2. Try to install Team Foundation Server, but I noticed that it requires sharepoint service to be installed first. The service seems already installed in this computer. So I didn't reinstall the sharepoint service. When I try to exclude the SQL Server Reporting ServicesWeb applications from share point service, the command throw exceptions. When I try to view the localhost/reports, the page has errors(Reports server Unable to generate a temporary class, CS2001: xxx.dll could not be found error CS2008: No inputs specified). xxx.dll refers to different dlls each time I request the page.

3. Uninstall Sharepoint and reinstall, still encounter the same problem.

4. Uninstall SQL Server 2005, I also noticed the ReportServer sites in IIS haven't been removed after uninstallation. So when I reinstall the SQL Server again, on the Report Server Installation Options page, I can't select Install the default configuration (default selection), instead the second option is selected which is no auto configuration(options are all grey out so I can't change the selection). After installation, the report server site get a no page found error.

I also noticed in IIS - Report Server(Stop) can't be start. I get a Parameter is incorrect error when I try to restart. There is two sites underIIS - Report Server(Stop) , they are Reports and ReportServer, they seems correct. But if right click the Report Server(Stop) and click Properties - Asp.NET tab. It point to the D:\Program Files\Microsoft SQL Server\InetPub\wwwroot\web.config. However, I can't find any web.config under Microsoft SQL Server\InetPub\wwwroot\. So it seems something missing there...

Please help... Any idea and suggestion are welcome!
