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.
