Without more information, it would be hard to say what's happening
here.  I ran into the exact same symptom last friday and it turned out
to be an MTU problem.  bumped the MTU of the client back down to 1500
(from 9000) and everything worked as expected.  turned out the switch
I was using didn't support the larger MTU.
