Enabling ECN (Explicit Congestion Notification) in Vista - James

From: James OHara

Open a command prompt as an adminstrator or you will get an error that request needs to be elevated.

Type "netsh int tcp show global"
this will show your current TCP/IP state

To enable ECN, in command prompt type:
"netsh int tcp set global ecncapability=enabled"

To enable CTCP (Compound TCP)in command prompt type:
"netsh int tcp set global congestionprovider=ctcp"

To verify changes Type "netsh int tcp show global"

Hope this helps

Jim
