I noticed on my servers that everytime I had a restart, the following events were placed in the eventviewer.

EventID : 1015
Source : EvntAgnt
TraceLevel parameter not located in registry; Default trace level used is 32.

EventID : 1003
Source : EvntAgnt
TraceFileName parameter not located in registry; Default trace file used is.

Solution

This problem occurs if you install the Simple Network Management Protocol (SNMP) service but you do not also configure this service. These error events are logged by the SNMP service when you restart the computer. If the Evntagnt.dll file is not configured for debug tracing when the SNMP service starts, these two warning events are logged.

To stop these events from occuring, add the TraceFileName and the TraceLevel values to the following registry subkey:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SNMP_EVENTS\EventLog\Parameters

TraceFileName
Type: REG_SZ
Value: null (blank)

You can also fill in a filename (eg. snmp.log) to log SNMP information. The logfile will be created under “%systemroot%\system32″. This registry key removes event ID 1003

TraceLevel
Type: REG_DWORD
Value: 32 (0×20)
This registry key removes event ID 1015
