Core concepts

Separate the layers of access.

1

Server licence

Licenses the Windows Server software installed on eligible hardware or virtual machines according to the selected edition and core rules.

2

Windows Server CAL

Provides a licensed user or device the right to access Windows Server services, subject to the applicable version and terms.

3

RDS CAL

Adds rights for Remote Desktop Services access. It is typically required in addition to the base Windows Server CAL.

Prepare the request

Information that makes guidance useful.

A clear environment description helps the source-store team identify which catalogue options warrant closer review.

  • Server version, edition and physical or virtual deployment
  • Total named users and total shared devices
  • Whether each user accesses from multiple devices
  • Whether devices are used by shift workers or multiple people
  • Existing CALs and any downgrade or version requirements
  • External users, contractors or service-provider scenarios
