Microsoft Windows Server 2019 User and Device CALs

Each user and/or device accessing Windows Server Standard and Datacenter editions is required to have a Windows Server Client Access License ( or CAL) to get access to the features they depend on such as file storage, domain access, printing, etc. A Windows Server CAL gives one user or device the right to access any edition of Windows Server of the same or earlier version per user or per device CAL purchased. User CALs are typically purchased for employees needing roaming access to your business network. Device CALs however, are preferred in terms of administration and cost if your company has workers that share devices on the same network.

Aventis Systems offers Microsoft Windows Server 2019 User and Device CALs in bundles of 5, 10, 25, and 50 CAL as well as single user and device client access licenses. Shop below today and ensure your employees have access to the features they need with Windows Server 2019 Client Access Licenses from Aventis Systems!
