Working with ASP.NET Applications
Topic Last Modified: 2007-01-30
Microsoft® ASP.NET is the next version of ASP and provides a new programming model and infrastructure for building scalable, secure, and stable applications. ASP.NET is a compiled environment based on the Microsoft .NET Framework and applications can be authored in any .NET-compatible programming language, including Microsoft C# and Microsoft Visual Basic® .NET.
The functionality of Collaboration Data Objects (CDO) Component Object Model (COM) components, CDO for Exchange 2000 Server (CDOEX), CDO for Exchange Management (CDOEXM), and CDO for Workflow (CDOWF) can be exposed to ASP.NET applications through the COM interoperability feature of the .NET Framework. The CDO COM components can also be exposed to remote applications and users through Web services.
By default, the worker process for ASP.NET (Aspnet_wp.exe) runs under the local machine account to restrict access to domain resources and provide a more secure environment. This will cause an error if you try to run or debug an ASP.NET application on a domain controller or a backup domain controller. On a domain controller, all user accounts are domain accounts and not local machine accounts, so Aspnet_wp.exe fails because it cannot find a local account named "localmachinename\ASPNET".
