I have noticed that once a week or even once a day all of the sensors lose connection on my primary domain controller. After about an hour it comes back on and everything is ok.
All the errors say that the connection Timed out or that there was no response.
I am running Windows Server 2008 R2.
The error is as follows:
"WMI: Connection could not be established (Port Error : RPC Server not accessible. - Host: lacpdc.lake.org, User: admin, Password: **, Domain: ntlmdomain:lake.org) (code: PE015) -- PerfCounter: Unable to connect to the specified computer, or the computer is offline. (Performance Counter error 0x800007D0)"
What causes this?
