well, the short answer is probably "no", as CreateDisposition flag is 
client chosed, as you've already found out yourself. Otoh, *something* 
seems to trigger the different behaviour and there may well be 
differences in server behaviour, so I would check everything server side 
that may affect wire behaviour starting at the top like checking basic 
configuration down to the bottom ie compare every bit on the wire with 
wireshark until you find the difference.
