We built a multirole Exchange 2010 server with CAS, HUB and Mailbox roles and moved it to a different AD site. We brought the server up in the new AD site, changed the IP, and registered in DNS but are experiencing a couple of issues:
1) The server is still showing up as a member of the CAS array for the original AD site it was in
2) Mail clients in the site where the Exchange server originally was are still using the server's Hub Transport services even after it's been brought up in a different AD site with a different IP. The mail is making it over to the server in the new site
but queuing up there.
