Add Users and Devices Efficiently With CALs
  • A CAL (client access license) gives a user or device the right to access Windows Server on your network via an authenticated connection
  • CALs are required for each user or device that accesses Windows Server 2016 Standard and Datacenter editions
  • CALs are version-specific and may be used to access the corresponding version of Windows Server or any previous version
  • User CALs deliver increased value and flexibility. With device proliferation there’s a growing trend of more devices per employee and it is easier to track users who can add devices at no additional cost
  • CALs are no longer part of the OS server license. They must be purchased separately
