I have working SSRS but am trying to access it from C# code using SSRS webservice. From what I know it should be something like http://server/Reports/ReportExecution2005.asmx for SQL2005 if install was with default values.
How do you test if your SSRS 2008 webservice up and running and / or accessible (ie not bloced by firewall)? What the URL look like ?
Look at below. Depends on if it is named instance or default instance.

You can use Reporting Services Configuration Manager (Either locally on the SSRS server or from a remote machine that has the Configuration Manager installed from SQL Server media) to check what base URL is used by the web service, the default is http://server/ReportServer/ if you can browse that URL with your browser the firewall is open and you should be able to connect to the webservice interfaces http://server/ReportServer/ReportExecution2005.asmx or ReportService2005.asmx
