Event ID 21 — BITS Server Configuration

  • Статья

Applies To: Windows Server 2008

Background Intelligent Transfer Services (BITS) server extends Internet Information Services (IIS) to support throttled, restartable uploads. To upload files to a server using BITS, the server must have IIS 7.0 on Windows Server 2008 and the BITS server extension ISAPI installed. The BITS server extension is a subcomponent of IIS, which is a subcomponent of Web Application Server.

To use the upload feature, create an IIS virtual directory on the server where clients can upload files. A virtual directory should be created for each type of client. BITS adds properties to the IIS metabase for the virtual directory created and uses these properties to determine how to upload the files.
