Trust your Lenovo Server to run Microsoft's proven operating systems, such as Windows Server® 2016, which have been fully tested for compatibility. Lenovo offers the Windows Server operating system - either pre-installed at the factory or as a Reseller Option Kit (ROK) - to fast-growing small businesses and demanding large corporations.
Many Microsoft servers not only need licencing, but server access is also required. For example, to access a Windows Server and Exchange Server, you need appropriate access licences that are assigned to either a user or a device. A Client Access Licence (CAL) enables you to licence the access of users and devices to Microsoft servers, whose licencing model requires that access to server software is separately licenced.
