SYMPTOMS

In a Microsoft System Center Configuration Manager 2007 site, the following discovery processes run much slower than in a Microsoft Systems Management Server 2003 site:
  • Active Directory System Discovery
  • Active Directory System Group Discovery

CAUSE

This problem occurs because the Discovery Data Manager (DDM) in Configuration Manager 2007 uses a complex query that takes more time to run. Specifically, Configuration Manager 2007 uses the fully qualified domain name (FQDN) of the discovered client as the Resource Name. Configuration Manager 2007 uses the Resource Name as the key property during the discovery process. This Configuration Manager 2007 functionality is intended to address issues that may occur when there are duplicate NetBIOS names.

RESOLUTION

To resolve this problem, apply the following hotfix on Configuration Manager 2007 site servers. After you apply this hotfix, you can disable the Resource Name marking behavior if it is not required for your environment. When you disable this behavior, the discovery process runs more efficiently. To disable this behavior, perform the procedure that is described in the "Registry information" section.

Registry information

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 How to back up and restore the registry in Windows
After you apply this hotfix, you can then make the following registry modifications on Configuration Manager 2007 site servers.

To disable the Resource Name marking behavior for the Active Directory System Group Discovery process, follow these steps:
  1. On a Configuration Manager 2007 site server, start Registry Editor. To do this, click Start, click Run, type regedit in the Open box, and then press ENTER.

    Note These steps to modify the registry are still required after you install System Center Configuration Manager 2007 Service Pack 1.
  2. Locate and then click the following registry subkey:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SMS\Components\SMS_AD_SYSTEM_GROUP_DISCOVERY_AGENT
  3. On the Edit menu, point to New, and then click DWORD Value.
