We are seeing the following errormessage in the systemlog on servers that has the SNMP features activated:
Log Name: System
Date: 2012-08-16 03:05:19
Event ID: 1500
Task Category: None
Description: The SNMP Service encountered an error while accessing the registry key SYSTEM\CurrentControlSet\Services\SNMP\Parameters\TrapConfiguration.
The solution (acatually a workaround) is to create the registry key mentioned above as it is missing. More information can be found in Microsoft KB Article 2002303, http://support.microsoft.com/kb/2002303
