Hello jhon,

From http://support.microsoft.com/kb/953230

What is the effective port range when the value of the MaxUserPort registry
entry is set explicitly?

The MaxUserPort registry entry has a different meaning in Windows Server
2008, in Windows Vista, in Windows Server 2003, and in Windows 2000 Server.

In Windows Server 2003 or Windows 2000 Server, the value of the MaxUserPort
registry entry defines the dynamic port range. The range starts from 1024
to MaxUserPort.

In Windows Server 2008 or Windows Vista, the value of the MaxUserPort registry
entry signifies the number of dynamic ports. The range is from Start range
(default is 49152) to Start range + MaxUserPort.

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.?
