Currently, we have one 2003 front-end server and three 2003 back-end servers.
We also have 2 CAS servers (2010) with a CAS Array. Today we run the commands below. We did not switch the namespace in DNS server. We used a workstation and modified the host file for testing the new 2010 OWA page to see if the user account on 2003 Exchange redirects to a 2003 OWA page. We noticed that the page (redirects)becomes blank when the user accont is on certain 2003 back-end servers. If the account is on back-end server called ex1, the redirect works. Any ideas??
