Licence-model decision
Choose User CALs when people outnumber their regular devices
Hybrid employees
One licensed person can access Windows Server services from an office PC, laptop or another work device.
Mobile teams
Useful when named employees move between locations and regularly use more than one endpoint.
Identity-based management
Track licensing by named user rather than tying the access right to a single shared device.

License ordinary access

Buyer questions
Windows Server 2016 Datacenter Server CAL FAQs
Does one supplied licence cover the selected CAL quantity?
Yes. One supplied licence record covers the 2, 5, 10, 20 or 50-CAL quantity selected above.
Is a Server CAL Windows Server Datacenter software?
No. It provides access rights for the licensed users. Windows Server 2016 Datacenter software and core licensing must be purchased separately.
Does one User CAL cover several people?
No. Each User CAL is assigned to one named user. Choose Device CALs instead when many people share a smaller number of fixed devices.
Can a licensed user work from several devices?
Yes. A User CAL follows the named user rather than one endpoint, subject to Microsoft's licence terms.
Do I enter this in Remote Desktop Licensing Manager?
No. Remote Desktop Licensing Manager is for RDS CALs. This page supplies base Windows Server access CALs; RDS CALs are purchased separately.
Are CALs different for Standard and Datacenter?
Windows Server CALs are version-based access licences and are not normally edition-specific. An appropriate Windows Server 2016 CAL can provide access to Standard or Datacenter of the same or an earlier version.
How many CALs should I buy?
Count every named user who requires licensed access to the Datacenter environment, then select the matching pack. Contact Software Mart if your environment mixes User CALs, Device CALs or RDS access.
