Microsoft NetMeeting is a discontinued VoIP and multi-point videoconferencing program offered by Microsoft; NetMeeting allowed multiple clients to host and join a call that included video and audio, text chat, application and desktop sharing, and file sharing. It was originally bundled with Internet Explorer 3 and then with versions of Windows from Windows 95 to Windows Server 2003.
History
NetMeeting was released on May 29, 1996, with Internet Explorer 3 and later Internet Explorer 4. It incorporated technology acquired by Microsoft from British software developer Data Connection Ltd and DataBeam Corporation (subsequently acquired by Lotus Software).
Before video service became common on free instant messaging clients such as Yahoo! Messenger and Windows Live Messenger, NetMeeting was a popular way to perform video conferences and chat over the Internet (with the help of public ILS servers, or "direct-dialing" to an IP address).
Protocol architecture
NetMeeting is an implementation of the ITU T.120 and H.323 protocol stacks for videoconferencing, with Microsoft extensions. A call is set up, undertaken, and torn down between NetMeeting clients using the H.225 protocol. Audio is carried using H.245, encoded using the G.711 and G.723.1 codecs from 5.3 to 64 kbit/s, while the video is encoded using the H.263 and H.261 codecs. Application sharing is performed using the "Share 2.0" protocol, based on a pre-release version of T.128, which is also used to transport chat messages. Whiteboard sharing utilizes ITU T.126, while file sharing is accomplished using FTP over T.127. Due to its use of a standardized protocol, NetMeeting can interoperate with other H.323-implementng software, such as Ekiga.
Discontinuation
In Windows XP, the Start menu shortcut to NetMeeting was removed "by design". Users had to start conf.exe manually from the Start menu Run dialog.
As of Windows Vista, NetMeeting is no longer included with Microsoft Windows. NetMeeting can still be installed and run on 32-bit versions of Windows Vista, as Microsoft published an update for 32-bit versions of Windows Vista on March 22, 2007, that installs NetMeeting 3.02 on Windows Vista Business, Enterprise, or Ultimate editions. However, some features are not available in 3.02, such as remote desktop sharing invitations (incoming) and whiteboard area selection. Microsoft has stated that the Vista-compatible version is unsupported and only meant as a transition tool to help support collaboration sessions when used with Windows XP-based computers. On Windows 7 Professional, Enterprise, or Ultimate, users can use Windows XP Mode to run NetMeeting.
Microsoft originally recommended using newer applications such as Meeting Space, Remote Desktop, Remote Assistance, Skype, Microsoft Office Live Meeting, and SharedView in place of NetMeeting. Skype for Business Server and Skype for Business (previously known as Office Communicator and Lync), and Microsoft Teams represent recent videoconferencing products from Microsoft, which may be considered successors to NetMeeting.
