-we upgraded our main domain controller from 2003 to 2008. When i say "main" i am referring to the DC that host our 3 catalogs. We have 2 other 2003 domain controllers on the network.
-we have not demoted the older 2003 DC yet
-the issue only happens when we power down the older 2003 DC (we currently keep it online for this reason)
-it does not matter if we connect to OWA on the local network or while off-site
-if the old dc is turned off and a user has their default address list set to one of the secondary address list then it goes back to the global address list.
-Outlook web access, and outlooks ssl(using http) both do not show the global address book.
-the "main DC" is also our DNS, WINS, and DHCP server. (if it matters)
-not sure if its related but when clients authenticate to the "site A" DC they do not show up in the network neighborhood.
It almost like there is a setting in exchange 2003 that needs to be set to the new DC however we cannot find anything.
