'Operation Timeout' encountered when deploying reports to Reporting Service (SQL 2008)

I have 4 rdl files (two very small (~20KB), two small/medium (~300KB)) that get deployed to the Reporting Service. I deploy them from within Visual Studio 2008. I have always been able to deploy the very small files (~20KB)...never a problem. But, encounter 'Operation Timeouts' for the files that are around 300KB. From what I have gathered from various forums and blogs, the size of report files (~300KB) should not be an issue here.

Also, I have the setting "<httpRuntime executionTimeout="9000" />" in the web.config for ReportManager and ReportServer.

Since the file sizes are nowhere near the (supposedly) 4MB size limit for uploading report files that a couple of blogs talked about, I did not try adding the attribute, maxRequestLength.

The only work-around (and this is possible only in the development environment) is to stop and re-start the SQL Reporting Service (Administrator Tools -> Services). Whenever I re-start the service, I manage to deploy one of the larger files. Once that is successful, I am again unable to deploy the other larger file due to an 'Operation Timeout'. As you can imagine, I have to stop and re-start the service again to deploy the other file! This is *absolutely* unacceptable in the TEST or PROD environments.

Please suggest what options I have to investigate and resolve this. Just FYI... this 'Operation Timeout' occurs is when deploying the reports NOT when executing them.

Thanks in advance.
