[Yann]

Hi,
i have like 400 PCs and the Dashboard of the LanSweeper report me some PC twice on the Primary domain and other on the Workgroup domain , i try to delete it because i suppose that for some reason appear before join on the domain but on this weekend they appears again.
How to FIX it because the report on the dashboard doesnt't give the true information.

Can you mail us your scanning setup please.

I'm guessing that you use IP scanning with "ignore windows" off and "workgroup" as default domain.
If this is the case change "workgroup" to the name of your domain.
