Re: New 2k3 infrastructure advice

sorry - should have been a bit clearer...all of our network is located
publicly (and has done so for years) as I am about to upgrade all of our
DCs/exchange etc so I am trying to see if it is worth while moving everything
over to a private lan for greater security. I plan on introducing ISA 2004 so
I can carry out multi-layer filtering (currently using a PIX) but can ISA
2004 still operate public --> public OR must it be public --> private. I
guess what I am trying to work out in my design of AD if I should I move
everything over to a private LAN or just leave it as is - I would just like
to hear peoples comments on the above bearing in mind that i plan to
introduce ISA 2004 - thanks
