firstly thank you for answer.. but The ideal way to host Windows Media files and streams is on a server running Microsoft Windows Media Services 9 Series. However, you can also host Windows Media files on any Web server. To stream from a Web server, add the Windows Media Multipurpose Internet Mail Extensions (MIME) type to your Web server, create simple Windows Media metafiles with .wax, .wvx, or .asx file name extensions in a text editor (such as Notepad), and then copy the content to your server. Any user can then connect to your site and play audio and video content with Windows Media Player. Later, when you decide to expand, you can add a Windows Media server to your Web site and take full advantage of the features and benefits that are available to you from Windows Media technologies. it mean is like online radio in ur server... but I told u we are in internet cafe.. and there is a lot of song... near 20.000 I think in Media server I have to work for them one by one for 20.000 mp3? and .asf video/x-ms-asf .asx video/x-ms-asf .nsc video/x-ms-asf .wax audio/x-ms-wax .wm video/x-ms-wm .wma audio/x-ms-wma .wmd application/x-ms-wmd .wmv video/x-ms-wmv .wmx video/x-ms-wmx .wmz application/x-ms-wmz .wvx video/x-ms-wvx if I delete all share folder and don't share anything.. how can let them watch movie's ? read e-book & document ? looking pics? etc... just I need when u connect to Network example \\hostmachine\sharedfolder\mp3 or \\hostmachine\sharedfolder\video's when u see folder just clicking and watching or listening... we don't wanna let our guest to copy them from hostmachine to which they are using currently. after that they are putting them usb stick.. we don't want this..but how? any suggestion ?
