Brian, 

I don't see your point with ASP Down...  :-/

If we go back to your first mail about this issue, the discussion was whether the ASP_INACTIVE state had to be achieved before deregistration by all means, or there could be some very strange situations where it can not be achieved. I showed you an example with the latter...

Therefore SHOULD fits. (unless you demonstrate the other...  :-D )

Cheers // Javier.
