SYMPTOMS
A Microsoft Windows 2000-based domain controller may experience a memory leak in the Wmiw paged pool tag in the kernel mode memory. This symptom occurs if the following conditions are true:
 * The domain controller is running a DNS server that is pointed to itself as either the preferred or the alternate DNS server.
 * The domain controller is replicating with at least one other domain controller in the domain.
 * Windows Management Interface (WMI) event tracing APIs are turned on in the domain controller.

Note All components of Windows 2000 Server mark allocated memory blocks with unique tags. The tags are used for monitoring allocated memory. The Wmiw tag identifies a paged pool buffer that is used for event notification. The leak in the paged pool may be at the rate of one allocation per three hours. The size of the allocation is 4,096 bytes.
