Verder kwam ik de volgende quote tegen:
As more companies deploy Windows 2008 and Vista, it is crucial, or in my opinion, critical that this hotfix be applied to all Windows 2003 servers that may communicate with these operating systems. One of the main reasons is a new feature called TCP auto-tuning which makes use of RSS to expand and shrink the sizes of your TCP window to increase/decrease throughput based on current network load. This feature greatly increases throughput on your network, but if there is an underlying problem with the network card driver or any of these features between disparate systems, you may experience slower than normal network performance. The good news is that the Chimney feature is disabled by default in Vista/Windows 2008.
