Hi Luqa, Are you referring to OpenManage Essentials(OME) or OpenManage Server Administrator(OMSA)?Looks more like OMSA. This forum is more dedicated towards OME, if you could move this post to the general systems management forum, you would get more help there. [URL]
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?  Luca
