TCP Windows scaling on Windows 2008 server

scalingtcpwindows 7windows-server-2008

If found only this article on windows 2008 server or Windows 7 TCP Windows scaling.

Is there any other information that I can use to change registry that would modify the TCP Window size?

Part of Vista and Server 2008 is a next-generation TCP stack... it's auto-tuned, so there is no more TCPWindowSize tweak.

As far as changing it, you can turn auto-tuning on or off with these commands...

netsh int tcp set global autotuninglevel=normal
netsh int tcp set global autotuninglevel=disable

Ok, some obvious ones, but maybe they can help:

Does the server correctly accept other inbound connections like file sharing, remote desktop and so on?
Does the service accept connections from the server itself, i.e. telnet localhost 40000?
Is the service a .NET application? Windows Server 2008 can get a lot tricky with .NET framework sub-features.
