You may experience the following symptoms when you start a 32-bit application in a 64-bit version of Windows Server 2003:

•	A delay occurs when you start the application.
•	The application consumes more memory space than it does in a 32-bit version of Windows Server 2003.

Back to the top

This problem occurs because of a collision between the following items in the 64-bit system:

•	The base addresses of some WOW64 binaries
•	The base addresses of the Kernel32.dll module and of the Ntdll.dll module

Windows Server 2003 performs an automatic rebasing action when the operating system detects a base address collision. The automatic rebasing action creates a private copy of the conflicting .dll files. This action delays the loading of these .dll files. Additionally, this action consumes extra memory space because a private copy of the .dll file is created for each process.

Technical support for x64-based versions of Microsoft Windows

If your hardware came with a Microsoft Windows x64 edition already installed, your hardware manufacturer provides technical support and assistance for the Windows x64 edition. In this case, your hardware manufacturer provides support because a Windows x64 edition was included with your hardware. Your hardware manufacturer might have customized the Windows x64 edition installation by using unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you must have technical help with a Windows x64 edition. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware. If you purchased a Windows x64 edition such as a Windows Server 2003 x64 edition separately, contact Microsoft for technical support.

For product information about Windows XP Professional x64 Edition, visit the following Microsoft Web site: For product information about x64-based versions of Windows Server 2003, visit the following Microsoft Web site:
