The work that has gone into 1.4.1 allows the file servers to track the
clients when the clients move. It does not allow the file servers to
communicate with clients when the network paths to the clients no longer
exist.
Windows clients running 1.4.0 when idle do not contact the file servers
but once per hour. During that time period the NATs will timeout the
port mappings. Hence the file servers will not be able to communicate
with the clients.
Windows 1.4.1 clients contact the file servers at least once per ten
minutes. This is better for most NATs but there are some that will
timeout the port mappings in under a minute for UDP.
With 1.5.1 (an unstable release) you can set the probe period via the
registry to under a minute if you so choose. Not that I recommend this.
I would need to see the output of the file server logs at level 125
to explain to you exactly what is happening. However, suffice it to
say that if your NATs do not keep the port mappings open, nothing the
file server does is going to help.

Thank you Jeffrey. That explains a lot about what's happening at least.
I will send along the file logs tomorrow. I'm assuming kill -TSTP will
achieve the level you require?
