We recommend that you have a look at both
this KB article about Domain scanning requirements and
this article about workgroup scanning requirements.
Computers aren't successfully scanned if there is an issue with Scanning credentials, Firewall, WMI on the target computer, possibly also the Lansweeper license.
If you can't resolve the issue, could you send a mail to support@lansweeper.com with the following information:
- The error log as present under Program Files (x86)\Lansweeper\Service\Errorlog.txt on your Lansweeper server
- The output of Program Files (x86)\Lansweeper\Actions\testconnection.exe after running it from your Lansweeper server to one or two client computers which were not successfully scanned. Provide the same credential to the testing tool that also Lansweeper is using.
- Screenshot of the Configuration\Your License page
We will follow up via mail.
