I am curious as to when the Rogue system detection fires off? We added a server and it took over 12 hours to see it. I thought there was a query that runs every hour but I couldn't find one. With that being said I did just founfd out that my rogue detection auto response was disabled. So I enabled it. So is tht the only thing there is?
And with all that being said, I do not see where to "ADD" a new rogue or server or desktop. There should be a way to add one manually.
The actual RSD detections are done by the sensors, and so usually happen pretty quickly. However sensors don't pass this information back to ePO immediately: this is most likely where the delay is coming from.
The intervals for reporting information back to ePO are configured as part of the RSD sensor policy - I'd have a look at how you have this configured and if necessary tweak the setting for your environment.
