Nice juicy one today, of course in my unfortunate true style, that being where I couldn’t find one darn person who is suffering the same error as me on the Interwebs. I’ve had a few of these lately, so I thought maybe I might be able to at least help others.
I had wired up a Crystal Report through a Web Form (actually embedded within an ASP.NET MVC Web Application) and loaded through the CrystalReportViewer across an ADO.NET DataSet.
All was merry on my development machine, the report loaded fine with no problems.
However, when deploying to our live server which was setup with the Crystal Reports Re-distributable Package for .NET Deployment, it was a different story.
The report was blank. Due to Crystal’s “brilliant” (cough) error reporting, I had no clue why the report failed to load other than just not seeing it. So I decided to check the Windows Event Log for any trails (as I’ve been caught out on this before) and low and behold there was our nasty exception:
Exception type: ConfigurationErrorsException
Exception message: It is an error to use a section registered as allowDefinition=’MachineToApplication’ beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. (c:\inetpub\wwwroot\aspnet_client\system_web\2_0_50727\crystalreportviewers12\web.config line 6)
Well for me, creating the application as a .NET application in IIS, was not my issue, this had already been done. The error after a bit of fiddling, I actually found out, was due to that Crystal Reports-issued Web.config mentioned in the exception (c:\inetpub\wwwroot\aspnet_client\system_web\2_0_50727\crystalreportviewers12\Web.config). It was conflicting with my application.
After spending some time with this file, I couldn’t get the error message to budge. So I took easy street, a good ‘ole rename. I humbly decided I did not need this file after looking through the properties, there were no mission-critical properties relevant to my app in there, so click, rename, voila, report online.
Hope this was your problem.
…Seems to me like a mildly tested Crystal Reports Re-distributable package could be to blame…

This was a great help. I have spent days working on this and finally I stumbled on this post and boom it started working. Many thanks for this post. Greatly appreciated!
Me too, glad I could help
hi,
i am on a sharing server and cant access machine web.config so how to fix it then
Hi,
My problem is a bit different, maybe you could help me. I have crystal report application built on asp.net vs 2005. The crystal is wired via storedprocedure. When users supply criteria, a popup dialogue box displays asking if user wants open or save report. Report displays as PDF.
Now this works fine. but as the report printing continues, after a while report stops displaying. but when i restart server (win server 2003), report starts again.
Any idea why report stops???
