Windows Media MIME Types – IIS and Apache

Microsoft Internet Information Server 3.0

If you are running Windows NT Server and IIS 3.0 and want to configure the MIME types, create a registration entry file with a .reg file name extension:

1. Open Microsoft Notepad or another text editor.
2. Type in the following text. (Do not cut and paste the text from the Web page.)



3. Save the file with a .reg file name extension.
4. Double-click on the file to add the entries to your registry.
5. After creating this file, stop and then restart all IIS services.


1. Ensure that you have server administration privileges. If you do not have these privileges, ask your server administrator to update these MIME type extensions.
2. Change directories to /httpd/conf.
3. Edit the file srm.conf.
4. Add the following lines to the end of the file, or to where the other AddType video/* entries are found:

AddType video/x-ms-asf asf asx
AddType audio/x-ms-wma wma
AddType audio/x-ms-wax wax
AddType video/x-ms-wmv wmv
AddType video/x-ms-wvx wvx
AddType video/x-ms-wm wm
AddType video/x-ms-wmx wmx
AddType application/x-ms-wmz wmz
AddType application/x-ms-wmd wmd

If you add these to the end of the file, make sure that the file ends with a blank line.
5. Save changes and quit the editor.
6. Restart the Web server.
