Configure MMS Proxy

UserNative Intune settingConfigureMMSProxySettings

Supported on Windows Server 2003, Windows XP, and Windows 2000 only

What it does

This policy setting allows you to specify the MMS proxy settings for Windows Media Player. If you enable this policy setting, select one of the following proxy types: - Autodetect: the proxy settings are automatically detected. - Custom: unique proxy settings are used. If the Custom proxy type is selected, the rest of the options on the Setting tab must be specified; otherwise, the default settings are used. The options are ignored if Autodetect is selected. The Configure button on the Network tab in the Player is not available and the protocol cannot be configured. If the "Hide network tab" policy setting is also enabled, the entire Network tab is hidden. This policy setting is ignored if the "Streaming media protocols" policy setting is enabled and Multicast is not selected. If you disable this policy setting, the MMS proxy server cannot be used and users cannot configure the MMS proxy settings. If you do not configure this policy setting, users can configure the MMS proxy settings.
