Hi Peter/List
We have been working on a client that has similar problems and is behind a
firewall also.
To add the keepalive setting to a windows machine, add an environment
variable to the machine named "NSR_KEEPALIVE_WAIT" and the value is in
minutes.

Re: [Networker] double FULL savesets from vmware client
To stop firewall timesouts from dropping your control connections which
are idle during most of a save, set the server tcp keepalive interval to
be less than the firewall timeout...
Typical firewall timeout rules are 60 minutes...
On a solaris server the command to set the keepalive interval to 30
minutes is:
ndd -set /dev/tcp tcp_keepalive_interval 1800000
(you can type it anytime but it doesn't persist across reboots, so it
needs to be scripted at system startup)
On windows there is a way to do it, but I don't know what that is.
