Outlook 2007 Prompts For Password On Domain Workstations, Autodiscover Fails

My server was migrated from SBS 2003 to SBS 2008. It is running Exchange 2007 Since that migration, all of my Outlook 2007 clients get prompted for a username and password when they open it. The Connecting To url in the login box is also incorrect and it reflects the old url.

I ran the test email auto-configuration and every step failed. I will list the failure codes in order below.
0x80040413
0x800c8203
0x80004005

There are a couple of reasons why this could happen.
I have covered the 3 main ones in my article here: http://www.experts-exchange.com/articles/Software/Server_Software/Email_Servers/Exchange/Outlook-continually-prompting-for-username-and-password.html

If you find the article useful please vote for it :)

Try the Exchange Service pack first, followed by the Kernel Mode Authentication

I had this after doing an SBS 2008 migration.  It went away after I installed Exchange 2007 SP 2, which you can do via this method:
