Default Behavior

SNMP Trap is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the SNMP Trap service is started, it is running as NT AUTHORITY\LocalService in its own process of snmptrap.exe. If SNMP Trap fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the SNMPTRAP service is not running because of the error.

Restore Default Startup Configuration of SNMP Trap

The SNMPTRAP service is using the snmptrap.exe file that is located in the C:\Windows\System32 directory. If the file is removed or corrupted, read this article to restore its original version from Windows 7 installation media.
