You experience a long delay when you try to view the DACL or the SACL security information for an object after you install Windows Server 2003 Service Pack 1

After you install Microsoft Windows Server 2003 Service Pack 1 (SP1), when you click the Security tab in the Properties dialog box of an object to try to view the users and groups in the discretionary access control list (DACL) or the system access control list (SACL), you experience a long delay.

This problem occurs in particular for lists that have many groups in them. When you open the DACL or the SACL, you may see many calls to the DRSCrackNames remote procedure call (RPC) function in a trace of the activity on the network. This RPC function calls target domain controllers on the primary domain and on other trusted domains.

This problem occurs because the ability to display the common name for groups was added in hotfix 818739. This behavior adds several round trips to the domain controllers where these groups are hosted and adds a noticeable delay when the lists are long.

Note Hotfix 818739 is included in Windows Server 2003 Service Pack 1. For more information about hotfix 818739, click the following article number to view the article in the Microsoft Knowledge Base:

Technical support for x64-based versions of Microsoft Windows

Your hardware manufacturer provides technical support and assistance for x64-based versions of Windows. Your hardware manufacturer provides support because an x64-based version of Windows was included with your hardware. Your hardware manufacturer might have customized the installation of Windows with 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 your x64-based version of Windows. 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.
