Registry keys to identify dynamic port range in Windows Server 2008

[jhon2008jhon]

Im using both Windows Server 2003 and Windows Server 2008. In Windows Server 2003 ephemeral ports set by the admin can be easily identify by using the the Registry values.In Windows Server 2003 , Epemeral lower range is 1024 and

it cannot be changed by the administrator. But in Windows Server 2008 the Ephemeral range , both the lower end and the higher end can be changed by the administrator(e.g.netsh int ipv4 set dynamicport tcp start=10000 num=1000). Here i'm not talking about the default port range for the windows server 2008.

So My application need to identify the ehemeral port range defined by the administrator in WS2008. So What are the relevent Registry keys to identify lower end and the higher end in Windows Server 2008.?
