A 5.1
BETA installer was posted
here. We recommend backing up your 5.0 database prior to upgrading or installing Lansweeper 5.1 on a test server.
Rename detection can be enabled by ticking "Detect when a computer has been renamed" under Configuration/Scanning Setup/Server Options. Windows computers will then be identified based on a combination of model, serial number and MAC address. Note that Lansweeper will not keep a history of computer names. Only the most recent (current) computer name will be stored.
