Resolution:
If a Linux scan node is in use:
- A user account must meet the following requirement:
- Local user account added to the Administrators group
- Run the following PowerShell command on the target Windows computer to allow basic WinRM authentication:
- winrm set winrm/config/service/auth '@{Basic="true"}'
- Ensure that DNS resolution is working fine. Check if scanning target using IP only works.
