I have just installed SQL Server 2008 and am having problems using Report Manager. Initially, I had problems accessing Report Manager so I removed the SSL identifies on both the web service and report manager website using the configuration manager.
This solved the problem of accessing Report Manager. However, if I now click on either the "Upload File" or "New Data Source" buttons in Report Manager I get the following error:
"Internet explorer cannot display the webpage".
Go to: C:\Program Files\Microsoft SQL Server\MSRS10.SQL2008\Reporting Services\ReportServer
Set value of "SecureConnectionLevel" to 0 (zero);
Restart your Report Server.
