A Windows Server Client Access License (CAL) is a legal entitlement that allows a user or device to access services and features of a Windows Server instance. Without a CAL, even if you own a Windows Server license, users or devices cannot legally connect to the server for functions like file sharing, printing, or remote desktop. Distivo provides genuine, EU-compliant Windows Server CALs for 2019, 2022, and earlier versions, ensuring your organization stays fully licensed.
Every user or device that accesses a Windows Server—whether for file storage, application access, or remote desktop—must have a CAL. This applies to both physical and virtual environments. For example, if you run Windows Server 2019 Datacenter and have 50 employees accessing shared folders, you need 50 User CALs. Distivo’s transparent licensing guidance helps you calculate exactly how many CALs you need, avoiding costly audits.
Windows Server Datacenter edition requires CALs for all users/devices, just like Standard. However, Datacenter includes unlimited virtualization rights. Distivo provides Windows Server Datacenter licensing calculators and CALs for both 2019 and 2022.
Distivo covers all versions. Check our product pages for specific CAL packs.
Distivo ensures every license is genuine, sourced from Microsoft-authorized EU partners, and includes VAT invoicing for full compliance.
