In Microsoft 2000 Exchange or later versions, the Microsoft Exchange Best Practices Analyzer inspects the hardware configuration of the computer on which the program is installed to determine whether the computer has eight or more physical processors.

If eight or more physical processors exist, the Analyzer tool verifies that the hotfix that is described in Microsoft Knowledge Base article 974065 is also installed.

The Mscordacwks.dll file must be the version that is described in Knowledge Base article 974065 or a later version. This hotfix helps to prevent issues that may occur when .NET Framework runs on a computer that has eight or more physical processors.

For more information, view Knowledge Base article 974065, FIX: A System.InsufficientMemoryException exception occurs when you are running a .NET Framework 2.0-based application.
