I am attempting to get a Windows Server 2003 SR2 machine w/ Exchange 2003 SP2 machine ready for a staged migration to Office 365. I am having issues w/ Outlook Anywhere not testing out correctly on the Microsoft Remote Connectivity Analyzer site. Here is what I get:

The RPC/HTTP test failed.

Tell me more about this issue and how to resolve it
The RPC_S_SERVER_UNAVAILABLE error (0x6ba) was thrown by the RPC Runtime process.
I changed the servername and host name above in this post as you will see. I have tried several items but can't seem to get it working the rest of the way. Any additional help is appreciated.
