The information in this article applies to:

  • Microsoft Windows XP Professional Service Pack 2 (SP2)
  • Microsoft Windows XP Home Edition Service Pack 2 (SP2)
  • Microsoft Windows XP Professional 64-Bit Edition (Itanium)

SYMPTOMS

When you use the Active Directory Service Interfaces (ADSI) IADs interface that is retrieved from the IEnumVariant::Next method to enumerate many group members, your Microsoft Windows XP Service Pack 2-based computer may become slow and unresponsive.

CAUSE

The IADs interface has a memory leak that occurs when the interface is retrieved from the IEnumVariant::Next method. The memory leak occurs during the reference count and leaks one reference count for each item. Subsequently, the IADs interface is leaked for every group member that is enumerated in the group.
