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:
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.
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.
