My sensors intermittently show "Connection could not be established (80070005: Access is denied - Host: server.domain.com)." Pausing and restarting the sensors resolves the issue temporarily. How can I fix this permanently?


Error 80070005 means that the Domain Controller / local Windows could not verify the credentials for the target computer. If this error shows up and vanishes again sporadically then we have no explanation at the moment, as PRTG only reports the error the Windows System has encountered.
