According to this official Microsoft post
You can "Reduce the client TCP/IP socket connection timeout value from the default value of 240 seconds"
And you can do this by adding the value "TcpTimedWaitDelay" to the registry location "
Windows 7 Enterprise 64 bit (which I am running) did not have that value by default, but I added it and set it to 30 and even 10 and haven't noticed any real change in the "time wait" delay of 240 seconds...
Who or what OS is that microsoft post referring to? It seems to be generalized towards all versions of microsoft server 2003 and up?
