SnmpMgrTrapListen API Returns "ERROR_SERVICE_NOT_ACTIVE" Error If You Are Not an Administrator (177868)

SYMPTOMS

When you write programs that call the SnmpMgrTrapListen API, an error number 1062 (ERROR_SERVICE_NOT_ACTIVE) may be returned if the caller is not a member of the Administrators group. This error can occur whether or not the Simple Network Management Protocol (SNMP) trap service is started.

CAUSE

This problem can occur because the SnmpMgrTrapListen API has been opening the service control manager database for all access (SC_MANAGER_ALL_ACCESS) to query the status of the SNMP trap service. This level can only be granted to members of the Administrators group.

RESOLUTION

The SnmpMgrTrapListen API now opens the service control manager database for SC_MANAGER_ENUMERATE_SERVICE to query the status of the SNMP trap service. If the service is not started, the API attempts to start it. The user of the API still needs to be part of the Administrators group to start the service if it is not started when the API runs. Or, the user can use the SetServiceObjectSecurity API to change the security for the SNMP trap service.
