Troubleshooting SNMP and WMI connections

If you experience connection problems when connecting to a device via the Web Task Manager, Web Performance Monitor, or any other WhatsUp Gold feature that uses WMI or SNMP, please consult the lists below to troubleshoot the problem.

Troubleshooting a WMI connection

Important: You must have administrative credentials to establish WMI connections. For more information, see Using Credentials. Also, see Microsoft article 875605.

For more information regarding WMI and connection problems, see Microsoft articles 389290, 389286, and the section entitled "I can't connect to a remote computer" in the Microsoft Script Center article, WMI Isn't Working!.

Troubleshooting an SNMP connection

Important: The SNMP Trap Listener must be enabled to collect data for the SNMP Trap Log. To enable the WhatsUp Gold SNMP Trap Listener, the Microsoft SNMP Trap Listener must be disabled. Also, be sure to open SNMP port 162 for incoming SNMP traps.
