Symptoms

When the Microsoft Host Integration Server Windows Management Instrumentation (WMI) providers are used to monitor systems that are running Microsoft Host Integration Server 2009, an access violation error occurs, and the Wmiprvse.exe process may exit unexpectedly. Additionally, an event that resembles the following is logged in the Application log:


Cause

This problem occurs because the HIS WmiSna (Wmisna.dll) and HIS WmiSnaStatus (Wmisnastatus.dll) providers are loaded in the same instance of Wmiprvse.exe. When the WmiSnaStatus provider is unloaded from memory, it cleans up some objects that the WmiSna provider also uses. The access violation occurs when the WmiSna provider tries to access one of the objects that were cleaned up when WmiSnaStatus was unloaded from memory.
