Disabling TCP Chimney in Windows Server 2003 and NIC Hardware

I'm currently dealing with a couple of 2003 servers that have hangs and unresponsiveness. While doing our deep dive on it we found that TCP Chimney is enabled in the OS but is disabled on the hardware. So the question is: Does TCP Chimney have to be disabled on both the OS and the hardware or does just disabling it on the hardware work to disable it in order to prevent the non-paged pool memory leaks?  

Some Diagnostic Data:
NIC: HP NC382i DP Multifunction Gigabit Server Adapter (2 running as a Team)
NIC Driver: bxnd52x.sys
Driver Version: 6.0.32.0

Thanks Rich and Tony! We will be disabling this at the OS level on a few to see if it will stop the leak and improve performance before we push out to the rest of the environment.
