Outlook 2007 on Vista x64 won't connect to Exchange 2007

Last Modified: 2012-05-07
I recently upgraded one of our machines to Windows Vista Ultimate 64-Bit and Office 2007 Professional.  Prior to this upgrade the OS was Vista Business 32-Bit and Office 2003 Pro.  With the old set up Outlook connected seamlessly to our Microsoft Exchange Server 2007 (Running 2008 Server).  Since the upgrade, all I get when trying to setup a profile is the following error.  I can connect to the mail server directly, Remote Desktop, or via a Ping.

"Outlook cannot log on.  Verify you are connected to the network and are using the proper server and mailbox name.  The connection to Microsoft Exchange is unavailable.  Outlook must be online or connected to complete this action."

I've read previous posts both here and abroad telling me to check my firewall, do outlook updates, etc, and I've been unable to clear this error.  I've created multiple profiles and have had no luck.  I even put in the old hard drive and launched it successfully running 32-Bit Business & Outlook 2003 as was previously installed.

Most recently I attempted statically assigning my network information because of a possible Network Gateway issue.  http://support.microsoft.com/kb/913843 .  This didn't change the error message either.

Thank you for help.
