SNMP/OpenManage/Ncentral Block on Windows Server Essential 2012 R2

Hi.

I experience problems on two Dell Servers with Windows 2012 R2 Essential and SNMP reporting.

We are using SNMP and OpenMange for reporting to Ncentral (monitoring system).

I tested and I know that configuration which I use only doesn't work on Windows 2012 R2 Essential and Dell Servers.

In Event Viewer I found it:

The SNMP Service encountered an error while accessing the registry key SYSTEM\CurrentControlSet\Services\SNMP\Parameters\ExtensionAgents.

Any suggestions?
