    On our test server if we set Storage to default location which is in C:\Windows\TEMP folder we get unauthorized access exception, would setting Storage to "C:/Temp" cause any security issues, or are there better standard locations for storing temp files?

    Telerik.Reporting.Services.ReportServiceConfiguration ReportConfiguration = new Telerik.Reporting.Services.ReportServiceConfiguration
            ReportResolver = new ReportFileResolver(HttpContext.Current.Server.MapPath("~/MyReports"))
                    .AddFallbackResolver(new ReportTypeResolver()),
            Storage = new Telerik.Reporting.Cache.File.FileStorage()

    Hi Anton,

    The recommended location used by the storage is the default windows temp folder and you would have to make sure that the IIS process has read/write access for this folder. To give access to the folder go to Properties - Sharing|Security options or change the used application pool's Identity through IIS Manager.

    Still, you can change the default folder using the second overload of the FileStorage and passing any custom folder location that the IIS process has access to.

    For more information, check Error registering the viewer with the service. Access to the path X is denied.

    Best Regards,
    Progress Telerik
