NOTE: Below applies to both the latest stable version and development release

On Windows Advanced Server 2003 SP1/2 (2k3 from now on ), WS is altering the
data that it handing over to the protocol drivers.
I noticed the pkt data on wire and also once it is in the NDIS miniport. But
the data displayed and handed over to protocol drivers is wrong making the
fabric connection not last for long.
I am using WS to capture FCoE traffic. This basically is making WS usability
futile under 2k3.
Winows Advanced Server 2008 doesn't seem to have thsi issue (2k8 is NDIS 6x
etc)
