Weekly Scan Not Happening

Hi,

 

We have a decent number of machines that have not had their weekly scan. The policy is applied to scan everyone Weds at 12.00, but I can see some machines going back more than one week since they last scanned completed. Some even have no entry in the last scan completed and some go back to early 2017. Machines are rebooted fairly often.

There over 750 machines in the OU in question and most are okay and doing their weekly scans, but as mentioned others are not

Thanks

  • Hello pdturbo80,

    Weds at 12.00
    is ambiguous
    - noon or midnight. The scan is a task scheduled at the specific time. If the time is missed the scan isn't started later. Furthermore only a successfully completed scan is logged under Last scan, failures, aborts, cancels are logged as errors. If he machine is shut down before the scan completes you have no indication that it started.

    Scan starts are logged to the endpoints' SAV.txt as well as the scan's log (scanname.txt). Thus inspecting the endpoint logs should give more insight.

  • Thanks for the reply. Should the time be adjusted to say 13.00hrs? When you say logged as errors, will it only show the last successful scan time? Reason beign I have a load of machines that scanned last week-and no`t this week. Any ideas please?

  • Hello pdturbo80,

    should the time be adjusted
    I can't tell which time would be best in your environment [:)]

    There are basically three possible outcomes for a scheduled scan (this also applies to a Full system scan from the console):

    1. the scan successfully completes (with or without detections, with or without scanning errors) - the Last scan completed and Last scan name columns are updated accordingly
    2. the scan is cancelled by an admin on the endpoint, stops because a threat has been found in memory, encounters an internal error which causes it to abort, fails in the initialization phase - in this case the mentioned columns are not updated, the errors are reported to the console (Scanning errors under Alerts and Error Details, and in the View Computer Details pop-up)
    3. the computer is shut down before the scan completes or the computer is not running at the scheduled time - there's no indication that the scan has started or the schedule has been missed

    In case 3. detections and errors encountered during the partial scan might have been sent to the console, there is no indication though that they are related to the scan.

    As said, the endpoints' logs will have a record that the scan has been started, SAV.txt has the complete history, scanname.txt is overwritten and contains only output from the last run.

  • Hi,

    Still having issues with this. I have logged a call with Support and sent numerous files, but now they are not even responding to requests for more updates on my ticket :(

    Here is the output of the last scan "desktop full scan schedule.txt" from a sample machine (last completed 19/07/17-The task scheduler says that when it last ran) Our weekly scans for Desktops/Laptops are set to run 12.00pm every Weds-yet quite a large number of machines are not doing this. Users here are not admin, so cannot cancel the scan
