-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Workstation version 4.0 
- Microsoft Windows NT Server version 4.0

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.

To resolve this problem, obtain the latest service pack for Windows NT 4.0 or
Windows NT Server 4.0, Terminal Server Edition. For additional information,
