You install Microsoft ASP.NET for the Microsoft .NET Framework 1.1 on Microsoft Windows Vista. You then create an ASP.NET page. You request the ASP.NET page, and the worker process stops responding. In this scenario, you receive an error message that states that the worker process was closed because of a Data Execution Prevention (DEP) violation.
Note ASP.NET for the .NET Framework 1.1 will not run on Windows Vista with Microsoft Internet Information Services (IIS) 7.0.CAUSEThis problem occurs because the .NET Framework 1.1 runtime does not support DEP. IIS 7.0 on Windows Vista only supports the full isolation ASP.NET process model. The full isolation ASP.NET process model requires that the no execute (NX) feature is enabled.
Note By default, the .NET Framework 1.1 is not included with Windows Vista.RESOLUTIONTo resolve this problem, apply the .NET Framework 1.1 Service Pack 1 (SP1). After you apply this service pack, ASP.NET 1.1-based applications can run under IIS 7.0.
