Steve,

Thanks for taking the time to clarify this. I noticed in my test lab that
once I ran the ADC wizard and it made a PF, Config & Receipeint CA to my
test 5.5 server and the intial replication completed, I then had to
reconfigure the CA's manually to the SRS service on the new 2003 exchange
server? Is this best practice?

Also, I planned on running the ADC from my Forest Root DC (xyz.com). Would I
create CA's to each 5.5 server in the other 3 sites as well? Each site is a
child domain, ie. melbourne.xyz.com and has it's own Exchange server whithin
a unique site, ie (Melbourne) or do I just need to establish a CA to the
first 5.5 & EXCH 2003 server so it can inject two-way changes into LDAP and
AD? I was thinking I had to establish 3 CA's to each exchange server in the
individual sites?

Thanks Again!

Roger
