SNMP - 1102


Description »
The SNMP Service is ignoring extension agent dll c:\path\to\ext-agent.dll because it is missing or misconfigured.
Data formatted as » WORDS
0000: 0000007e 

The data gives away what's happening here. The data shows 7E, which is 126 in decimal. Winerror.h defines error 126 as 'The specified module could not be found.'

The description text tells you the path to the DLL, and you should find it is referenced in the registry under HKLM\SYSTEM\CurrentControlSet\Services\SNMP\Parameters\ExtensionAgents. Unfortunately, these values point to other registy keys - not directly to agent DLLs themselves. For example, the value with the name CPQHOSTSNMP points to System\CurrentControlSet\Services\CqMgHost\CPQSNMP, which contains a value called PathName, which points to C:\Windows\system32\CpqMgmt\Cqmghost\hostmib.dll.

To resolve this issue, you need to repair (reinstall) the agent in question, or remove the reference to it from the SNMP\Parameters\ExtensionAgents area of the registry.

No restart of the SNMP service should be necessary if you are removing the reference. Once you have modified that part of the registry, you should find an event with ID 1004 from SNMP in your System log, telling you that the configuration has been updated.
