discovery device history statuses

Ravish Shetty · ‎07-22-2019

hi all,

we are seeing some of these statuses for the discovery for windows servers from the device history. any known reason for these apart from credentials not authenticating?

Active = There were classification ports open

Active couldnt classify = We saw the classification ports open but when we tried to authenticate it failed

Active couldnt classify, no wmi connection = We saw port 135 open but when we tried to talk WMI no response was given.

Alive, not active, not classified = No Classification ports were open but we got some level of response such as refused.

Hope that helps.

You need more than just port 135 open, that's just the front door.. .Remember WMI Discovery requires the high ports open as well.
