3.8. Microsoft SAL (RDS SAL)

Microsoft SAL (RDS SAL) is a service that provides a Microsoft Remote Desktop Service Subscriber Access License (called an “RDS SAL” below) on Virtual Machines created in Compute Resource. This makes it possible for three or more users to connect to a remote desktop (Remote desktop session host server. Windows Server) for a specific Virtual Machine in Compute Resource.


  • In Microsoft SAL (RDS SAL), NTT Communications provides RDS SALs as its own service, based on a contract signed under Microsoft’s SPLA license agreement.

3.8.1. Available Features

You can use the following features in Microsoft SAL (RDS SAL).
Provided Feature Feature Overview
Provision of an RDS SAL A feature that uses an RDS SAL to allow a remote desktop connection for three or more users for a specific Virtual Machine (Windows Server) in Compute Resource.
Provision of a Public Catalog A feature that uses a template of the Virtual Machine to provide the above license.

3.8.2. Provision of an RDS SAL

The RDS SALs provided by Microsoft SAL (RDS SAL) are shown below.
Item Details
Version Windows Server 2008 R2 Remote Desktop Services SAL
Quantity 10, 30, 50, or 100
Type User SAL

It is necessary to match the OS version of Session Host Server and RDS SAL version of Remote Desktop License Server. As the current RDS SAL version of Remote Desktop License Server is Windows Server 2008 R2, the only available OS License for Session Host Server would be “Windows Server 2008 R2.”

3.8.3. Provision of a Public Catalog

You can use the templates provided by the RDS SAL to create a Virtual Machine (remote desktop license server).
You can use templates from the Customer Portal when creating a Virtual Machine in Compute Resource or Compute Resource (Dedicated Device).


  • An RDS SAL is only provided for a Virtual Machine created using the provided template (called a “Virtual Machine created with Microsoft SAL (RDS SAL)” below).

  • One RDS SAL and one OS license are provided as a set for one Virtual Machine created using Microsoft SAL (RDS SAL).

    The OS that is provided in the set is “Windows Server 2008 R2 Enterprise Japanese/English (64 bit version).” For details regarding the conditions for providing an OS license, refer to “3.4 OS License”.


  • Templates exist for each Data Center and are stored in the Public Catalog, which can be accessed by all users of that Data Center.

3.8.4. Important Points

  • The required number of licenses is the “number of total users that might connect,” not the “number that will connect at the same time.” Failure to purchase enough licenses is a license violation.
  • We recommend use in a domain environment with the specifications formulated by Microsoft.
  • To increase or decrease RDS SALs, add or delete servers. Please add or delete the servers yourself. NTT Communications cannot perform these features.
  • The system requirements (number of vCPUs, Memory capacity, and Disk capacity) for the Virtual Machine (remote desktop license server) are listed below.
Item Quantity
vCPU 1 or more
Memory capacity 2 GB or greater
Disk capacity 80 GB or greater

  • For information on settings for the remote desktop session host server, refer to the user’s manual provided by NTT Communications.
  • Setting up a remote desktop session host server in an On-Premises Environment to ask a Virtual Machine (remote desktop license server) created using Microsoft SAL (RDS SAL) for a RDS SAL is prohibited based on the license restrictions.

  • Duplicating and using the software without notifying NTT Communications.
  • Using Microsoft SAL (RDS SAL) to duplicate the image of the Virtual Machine that you are running and then running it as another Virtual Machine without notifying NTT Communications.
