Queries to SNMP devices stop responding when Windows Server 2008-based systems or Windows Vista Service Pack 1-based systems receive multiple SNMP WMI queries at the same time

This article has been archived. It is offered "as is" and will no longer be updated.
When a Windows Server 2008-based system or a Windows Vista Service Pack 1 (SP1)-based system that has the Simple Network Management Protocol (SNMP) Windows Management Instrumentation (WMI) provider feature enabled receives multiple SNMP WMI queries at the same time, queries to SNMP devices stop responding. The queries do not return data. WMI queries for SNMP devices fail.
The problem occurs because of the SNMP WMI provider. A deadlock situation occurs when the SNMP WMI provider handles multiple WMI queries at the same time.
