Hmmm, I think we are going to need a little more info.

1. What were you using to test?

2. Is the problem a server-only problem, or is it in the combination?

   That is, if you use smbclient to push or pull files to/from 
   Samba servers of the same versions as above, do you get the 
   same results?

3. It might be good to see some network traces.
