Generate Excel File using c# error deploying on Server RRS feed

  • Question

  • Hello,

    We are trying to generate Excel file using ASP.Net C# and I was able to generate the file on the Development machine but when I try to deploy its giving me an unauthorized access error.

    Server: Windows 2003

    .Net Framework 2.0

    Installed MS Office 2010 on Server and Microsoft Interop Assemblies.

    If I impersonate with specific user account its working but I don't want to be a fixed user account.

    I really appreciate any help...!

    Error:

    Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005.

    Exception Details: System.UnauthorizedAccessException: Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005.

    ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

    To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

  • Hi,

    Create dedicated application pool for site and switch its identity to "Network Services" and "Network Services" in ACL permission.

    This will solve the issue.
