Ditto the above. The system is currently a mess. No offense intended, but from your posts it ia painfully obvious that anything that you do is likely to make things worse, not better.
How much will it cost if you manage to take the system completely down and/or blow some of the components of the system?
How much is your boss paying you to try to figure this out and how long will it take you?
This is an obvious case of "penny-wise, pound foolish".
I would say that there is about a 50/50 shot that, with your very limited knowledge, that you will manage to eventually, in the next few MONTHS, get this mess straightened out. Pay a competent tech, get it done right the first time.
