SYMPTOMS
After you add the EnhancedSecurityLevel registry key, you may not be able to see or access any queues from MQExplorer. Also, you may not be able to send messages to queues on the computer where this registry entry is enabled.
CAUSE
When this registry key is enabled, the caller of the object is verified to be in Kernel mode, or that the access requested for the object matches the access when the object was opened. In this case, the access that was requested was not identical.

MORE INFORMATION
The EnhancedSecurityLevel registry key is set in the registry under the following key:
