ASP.NET 4.0 – An error occurred during local report processing

After fixing missing ReportViewer redistributable, I got the following error:
Report Viewer Configuration Error The Report Viewer Web Control HTTP Handler has not been registered in the application's web.config file. Add to the system.web/httpHandlers section of the web.config file, or add to the system.webServer/handlers section for Internet Information Services 7 or later.

An error occurred during local report processing.
The report definition for report 'C:\inetpub\wwwroot\some_path_to_report\tse.rdlc' has not been specified
Could not find file 'C:\inetpub\wwwroot\some_path_to_report\tse.rdlc'.

It turned out that Visual Studio 2010 C# / ASP.NET does not include .rdlc files when publishing application. This can be solved by going to the your_file.rdlc properties, and changing ‘Build Action’ from ‘Embedded Resource’ to ‘Content’.

Here is a screen-shot:

I forgot to install Microsoft ReportViewer 2010 Redistributable.

It also can be installed from the following location:
C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper\Packages\ReportViewer\ReportViewer.exe

Microsoft Report Viewer 2010 Redistributable Package Setup is easy 3 step process:

Microsoft Report Viewer 2010 Redistributable Package Setup
Microsoft Report Viewer 2010 Redistributable Package Setup 2
Microsoft Report Viewer 2010 Redistributable Package Setup Finished

VMware Guest OS: The trust relationship between this workstation and the primary domain failed

VMware Guest OS: The trust relationship between this workstation and the primary domain failed.

I received this errors two times on a row for two different computers.

I am not 100% sure, but from reading the web I came to conclusion that this error is encountered when:

  1. SID gets cloned when computer gets cloned using VMware. Not right after cloning, but at the random after some time.
  2. Guest OS gets reverted to some earlier snapshot.

In both cases leaving and joining Domain again fixes this issue.

P.S. Some time ago there was an utility called NewSID, but now it’s gone. NewSID has been retired and is no longer available for download. Please see Mark Russinovich’s blog post: NewSID Retirement and the Machine SID Duplication Myth.
