Permissions problems with ASPNET account

I am encountering problems when trying to access Microsoft's MapPoint from Visual Basic embedded in a web page. The following error message is displayed when attempting to access the webpage: ============================================== Exception Details: System.UnauthorizedAccessException: Access is denied. The ASP.NET process is not authorized to access the requested resource. For security reasons the default ASP.NET process identity is '{machinename}ASPNET', which has limited privileges. Consider granting access rights to the resource to the ASP.NET process identity. To grant ASP.NET write access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the "{machinename}ASPNET" user. Highlight the ASP.NET account, and check the Write box in the Allow column. ================================================= The following is the "Hello World" equivalent webpage that produced the error message above: ================================================== <%@ Page Language="vb" AutoEventWireup="false" Codebehind="WebForm1.aspx.vb" Inherits="WebApplication1.WebForm1" Trace="True" aspcompat=true Debug="True" %> <% Dim objApp objApp = Server.CreateObject("MapPoint.Application") 'Dim objConn 'objConn = Server.CreateObject("ADODB.Connection") %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title>WebForm1</title> <meta name="GENERATOR" content="Microsoft Visual Studio.NET 7.0"> <meta name="CODE_LANGUAGE" content="Visual Basic 7.0"> <meta name="vs_defaultClientScript" content="JavaScript"> <meta name="vs_targetSchema" content="http://schemas.microsoft.com/intellisense/ie5"> </head> <body MS_POSITIONING="GridLayout"> Hello World </body> </html> ================================================== Notes: 1) When I comment out the code that accesses MapPoint and unccoment the database code it works fine suggesting the problem is specific to something related to MapPoint. 2) I have included MapPoint in the "References" for this project in Visual Studio. 3) I get the problem even when I give the "Everyone" group full permissions to the MapPoint directory in C

rogram Files. 4) The ASPNET account is running as a member of the "User" group. 5) My environment consists of a) a fresh installation of Win2000 brought completely up to date with service packs b) a fresh installation of Visual Basic .NET along with Service Pack 1 c) a fresh installation of MapPoint 2002 d) no other software installed on this computer My questions are: 1) What is likely to be the file/whatever that the ASPNET account is attempting to access but does not have rights to access? 2) If a likely candidate in question 1) cannot be identified how does one go about determining (via debugger, logs, etc.) to what access was denied? 3) Is this likely to be a configuration problem in ASP.NET, IIS, MapPoint, or the application? Any pointers will be appreciated.provider permissions to that assembly. you can do this from the .NET Framework configurations in your administrative tools.
