To make sure that your content is available to all client versions that connect to your server, open all ports described in the table for all of the connection protocols that might be used during protocol rollover. When you install Windows Media Services 2008 on a computer that is running Windows Server 2008 or Windows Server 2008 R2, the Windows Media Services program (wmserver.exe) is added as an exception in Windows Firewall to open the default inbound ports for unicast streaming, and manually opening ports in the firewall is not required. For more information, see Windows Firewall Settings for Windows Media Services.
