As I mentioned earlier I had the same behaviour a few days ago.
I got the "phenomenon" :-) last night again.

It's exactly the same behaviour described by Nathan.
I did a tcpdump and noticed the fileserver was sending that client 
callbacks and the client responded. Which means the two machines are 
communicating. (network is OK)
So It might just be somewhere else.

BTW my client is in the same subnet even on the same switch.
