Outlook Anywhere on Windows 2008 not working

I am trying to setup Outlook Anywhere on a windows 2008 server.  I have a Go Daddy SSL certificate that points to mail.companyname.com.  I have my OA setup for Basic Authentication.  I have gotten this to work on a Windows 2003 server, but cannot get it to work on a Windows 2008 server.  When I open up outlook, the username box will not accept the password.

This is typically due to IPv6:

How to resolve.    Additional steps would comment out the localhost for the IPv6 in the host file.     I then added two IPv4 hosts for the local name and FQDN:         localhost  
# ::1             localhost       EXCHANGESERVER       mail.mydomain.com  
From here I added a registry key:  
With 0xff  
And then rebooted&then successfully tested Outlook Anywhere/Active Sync.  
Unlike Windows XP and Windows Server 2003, IPv6 in Windows Vista and Windows Server 2008 cannot be uninstalled. However, you can disable IPv6 in Windows Vista and Windows Server 2008 by doing one of the following:          
In the Network Connections   folder, obtain properties on all of your connections and adapters and clear the   check box next to the Internet Protocol version 6 (TCP/IPv6) component   in the list under This connection uses the following items.  
This method disables IPv6 on your   LAN interfaces and connections, but does not disable IPv6 on tunnel   interfaces or the IPv6 loopback interface.            
Add the following registry value   (DWORD type) set to 0xFF:  
This method disables IPv6 on all   your LAN interfaces, connections, and tunnel interfaces but does not disable   the IPv6 loopback interface. You must restart the computer for this registry   value to take effect.        
For additional information about the DisabledComponents registry value, see Configuring IPv6 with Windows Vista.  
If you disable IPv6, you will not be able to use Windows Meeting Space or any application that relies on the Windows Peer-to-Peer Networking platform or the Teredo transition technology.
