Hello Tiffany,
This is Koen from Lansweeper Support.
Since the webserver asset is not scanned as a Windows computer, we would think the scanning requirements for Windows scanning are not met (at least not on that IP address). We could help you troubleshoot this a bit more in-depth or help you set an exclusion. Please reach out to us on support@lansweeper.com.
Kind regards
The Lansweeper Support Team
