My money would be on a driver bug.  I've seen instances where
drivers work with MS servers but fail on Samba boxes due to the
fact the the driver doesn't NULL terminate REG_SZ values.
The Windows server just happens to use a different buffer
size and zeros the memory before sending the reply.  Could
be something similar here.
