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.?
I know the one is MaxUserPort, but not sure of the low end. I would test and monitor trying "LowUserPort" or "MinUserPort." But whether you know the low end key or not, you can set it with the netsh command. See this for more info:
Quoted: "To comply with Internet Assigned Numbers Authority (IANA) recommendations, Microsoft has increased the dynamic client port range for outgoing connections in Windows Vista and in Windows Server 2008. The new default start port is 49152, and the default end port is 65535. This is a change from the configuration of earlier versions of Microsoft Windows that used a default port range of 1025 through 5000."
The default dynamic port range for TCP/IP has changed in Windows Vista and in Windows Server 2008
