When you start the Active Directory Users and Computers snap-in or the Active Directory Sites and Services snap-in on a Windows Server 2003-based computer, the snap-in closes unexpectedly the next time that you open it

Consider the following scenario:

• On a Windows Server 2003-based computer, you open the Active Directory Users and Computers Microsoft Management Console (MMC) snap-in or the Active Directory Sites and Services MMC snap-in.
• You expand the current domain, and then you click some sub-nodes in the console tree.
• You click the Back button (the left arrow) on the toolbar.

In this scenario, all columns in the details pane except the Name column are missing.

When this problem occurs on a computer that is running an x64-based version of Windows Server 2003, the MMC snap-in closes unexpectedly (crashes) the next time that you open it.

This problem occurs if the MMC configuration file for the MMC snap-in is corrupted.

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.
