Ok, I think I'm looping here ;-)
Two questions.
First, how does this statement from the TCPIP Planning and Config
quide relate to how I define the IOCP statements?

Question two,
Isn't this what we have in the IOCP
etc. (which is giving us the unit
checks) from our original posting?
If not, what are we not seeing?
Thanks for trying to untangle my old synapses. ;-)
