For a Windows Server 2008 (not R2) I would like to set the TCP Initial Congestion Window Size. It would be similar for what could be done with R2 in this KB,http://support.microsoft.com/kb/2472264. Anyway to change this value? Thanks.

Hi RR1231, Thanks for posting here. Windows server 2008 (no R2) will not benefit by the changing in this hotfix, so please consider wither applying R2 to your server or enabling CTCP (Compound TCP) on it: Performance Enhancements in the Next Generation TCP/IP Stack http://technet.microsoft.com/en-us/library/bb878127.aspx Explicit Congestion Notification (ECN) for TCP/IP http://technet.microsoft.com/en-us/library/bb878122.aspx Thanks.
