Microsoft Servers系指Microsoft所发展的服务器产品线，旧称为Microsoft BackOffice，后有一度改称为.NET Enterprise Servers（推广Microsoft .NET平台策略时期）与Windows Server System（Windows Server 2003时期），虽然它是服务器产品线，但它和Microsoft Dynamics和Windows Server是不同的产品线。

Microsoft Servers (previously called Windows Server System) is a brand that encompasses Microsoft's server products. This includes the Windows Server editions of the Microsoft Windows operating system itself, as well as products targeted at the wider business market. Unlike Microsoft Dynamics or Microsoft Office product lines, most of the products sold under this brand are not intended to be line-of-business services in and of themselves.
