I'm upgrading my organization from Windows 2000 domain with Exchange 2000 to windows 2008 domain with Exchange 2007.
I've added two new servers to my site: one with Windows 2008 server to be AD and another to be Exchange.
I join the new DC to the existing forest and moved all AD rules to it.then I installed the exchange 2007 on the second server and join it to the existing exchange 2000 organization.
every thing went well but the OWA on the exchange 2007 doesn't work. I'm able to put a user name and password but I'm not getting a GUI screen only a text screen with the directories of my outlook and I can't get into any of them.
My Exchange 2007 server is enterprise edition and I've installed the exchange rollup 7 from windows update. I even uninstalled the CAS and re-install it again but i'm getting the same result. another thing is if I'm working with forms registration I getting a blank page with reason 0 error.
What am I doing wrong?
