TCP does re-send packets. TCP sits on top of IP and
provides connection services.
It is up to the stack implementation
to track packets and re-send the missing ones. We have seen
several instances of problems with the Novell stack for which
patches have been provided. I don't know what the current
Novell TCP patch level is, but it is vital to ensure that
you're at the latest level.
