SYMPTOMS

Consider the following scenario:
  • You create network shortcuts in My Network Places in Windows Server 2003 or in Windows XP.
  • You browse the subfolders of the network shortcuts in the left tree view of Windows Explorer.
In this scenario, the Explorer.exe process leaks handles. If you monitor the handle count of the Explorer.exe process by using the Performance Monitor tool (Perfmon.exe), you see that the handle count increases as you browse the subfolders. Eventually, the Explorer.exe process runs out of handles and stops responding (hangs).

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.
