SYMPTOMS
Microsoft System Center Operations Manager 2007 cannot find some network devices by using the network device discovery process. Therefore, you cannot manage these network devices in Operations Manager 2007.

This problem occurs even though the network devices respond to the &quot;GET&quot; packets that the Snmputil.exe tool sends.



CAUSE
This problem occurs because Operations Manager 2007 supports only version 2 of the SNMP protocol (SNMPv2). Devices that do not support SNMPv2 ignore the &quot;GET&quot; packets that Operations Manager sends. Therefore, the network device discovery process cannot detect these devices. For example, this situation occurs when the devices support only version 1 of the SNMP protocol (SNMPv1) or version 3 of the SNMP protocol (SNMPv3).

The Snmputil.exe tool uses both SNMPv1 and SNMPv2. These devices respond to the &quot;GET&quot; packets that the Snmputil.exe tool sends even if the devices support only SNMPv1.



RESOLUTION
To resolve this problem, apply the following hotfix. To do this, follow the steps in the &quot;Hotfix installation instructions&quot; section.

After you apply this hotfix, a new Simple Network Management Protocol (SNMP) Community version list appears in the network device discovery wizard. This list contains an SNMP v1 item and an SNMP v2 item. If you select SNMP v1 from the list, the network device discovery wizard uses SNMPv1 to detect network devices.
