Are you using a third party control in your reports? What version of SQL Server including Service Pack are you using?

Hi Matelin, Based on the error message, the issue is most likely a permission problem between the web application and the rdlc file. When you run the code from your local machine, this will be the MyComputer zone, but when you run it off of a server, or even a network share mapped to a drive on your machine, it will be the LocalIntranet zone. By default any code that is run from the MyComputer zone will get a permission set of FullTrust (unrestricted permission to do anything it pleases). However, by default, there is a more restrictive permission set given to LocalIntranet assemblies. For detailed explanation and solution, please kindly refer to the article below, My application works from my local machine, but throws a SecurityException when I move it to a network share: http://blogs.msdn.com/b/shawnfa/archive/2003/06/20/57023.aspx If you have any question, please feel free to ask. Thanks, Eileen

Sorry for late reply, the problem is a permission issue as Eileen says but the explanation is as follow: local reports must run in an application with a full trust level ,for details about application trust level, i found this good article: http://www.4guysfromrolla.com/articles/100307-1.aspx and my hosting company which is godaddy by the way, runs its shared hosting accounts in a medium trust level,so i wrote to the support for workaround and this is the reply i got: <-- You may downgrade to ASP.NET 1.1 to make use of Full Trust on our shared hosting plans. You may also switch to a Virtual Dedicated Server or Dedicated Server to use full trust as well. At this time, is no work around. All hosting accounts with 2.0-4.0 ASP.Net are set to Medium Trust and we do not allow Full Trust on these accounts. --> so i could not change the application trust level, and i could not found any valid solution to run local reports on a medium trust, if any one have found a solution to run local reports in a medium trust please reply,if not i have to change my hosting company.Matelin

Hi Matelin , You are right, local mode requires full trust. Remote mode only requires medium trust. Additionally, if you have any concern about this, please submit a feedback at http://connect.microsoft.com/SQLServer/Feedback and hope Microsoft improve this feature in the next service pack or product release. Thanks for your understanding. Thanks, Eileen
