Programs that require lots of memory may not run after you install Windows Server 2003 Service Pack 1

On a computer that is running Microsoft Windows Server 2003 with Service Pack 1 (SP1) or an x64-based version of Windows Server 2003, you may experience the following symptoms:

• Web programs that must allocate 1.3 gigabytes (GB) of contiguous memory may not work.
• The ISAPI filter cannot allocate more than 1 GB of memory.
• You may receive an error message that resembles one of the following:
  • Not Enough Memory
  • Out of memory
  • Not enough storage

This problem occurs because the Xpsp2res.dll file does not specify its base address. Therefore, the .dll file is loaded into memory at location 0x10000000. This configuration prevents much memory from being allocated to programs. Therefore, the virtual memory that is available to the programs is fragmented.

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 need 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 Microsoft Windows Server 2003 x64 edition separately, contact Microsoft for technical support.
