Thanks All.
Pretty much exactly what i was thinking, so its good to know i'm not
loosing my marbles.
Problem was i wasn't consulted at design time.
We are doing a proof of concept as the design has already been
"approved" apparently and we shouldn't be changing it on theories. Pah.
I can't wait for the big fat "Told you So!"
Even if it works on one box its not going to work on all 6 i'm sure, and
even if it does i'm not signing off on it for SLA for support team as
its not a way to be doing a fully supported DR approach.
Cheers
