We've discovered that some of our PCs have been configured to pull their IPs from DHCP, but have DNS configured statically. Is there any way to check for this in Lansweeper?
Unfortunately, this is not something Lansweeper scans. However, if they have all have a specific static DNS configured, you can create a report with tlbNetwork.DNSServerSearchOrder with that specific IP as a criteria. That will at least narrow down the list of assets which might have a static DNS set.
