Windows Media Services (System Services for the Windows Server 2003 Family and Windows XP Operating Systems)

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

Service Name: WMServer

Executable Name: Wmserver.exe

Description: Windows Media Services provides streaming media services over IP-based networks. It replaces the four separate services that comprised Windows Media Services versions 4.0 and 4.1:

  • Windows Media Monitor Service

  • Windows Media Program Service

  • Windows Media Station Service

  • Windows Media Unicast Service

Windows Media Services is now a single service that runs on the Windows Server 2003 family. Its core components were developed by using the Component Object Model (COM), creating a flexible architecture that is easily customized for specific applications. It supports a greater variety of control protocols, including Real Time Streaming Protocol (RTSP), Microsoft Media Server (MMS) protocol, and HTTP.

The Windows Media Service platform is compliant with the following industry standards:

  • WMI for server event notification and messaging

  • SNMP for networking components

  • XML, Synchronized Multimedia Integration Language (SMIL) 2.0, and the Document Object Model (DOM) for playlist implementation

  • MPEG 1 and 2 for audio and video formats

Most streaming scenarios can be accomplished by using the core components installed with Windows Media Services. However, more advanced scenarios might require that you incorporate some custom programming and integration work. For developers and systems integrators, the Windows Media Services Software Development Kit (SDK) provides access to all elements of the server through a combination of plug-ins, a fully documented object model, and a rich set of external event notifications, all designed to be easily customizable.

If this service is stopped or disabled, streaming media services might be unavailable.
