Thanks, Justin. Those were good suggestions. Here are the results:
I ran ipconfig /flushdns and it flushed successfully
I deleted the c:\arcgisserver directory and all of its contents
At the command prompt, hostname returned "phantom" (which is the name of my computer)
At the commend prompt, ping -a 127.0.0.1 returned a ping from "phantom"
I am going to recreate the VM and not rename it to see if that makes a difference. That is the only thing I can think of at this point that was different from the Windows Server 2008 Data Server installation (I renamed the computer "hornet" after AGS was successfully installed and the site created.
Thanks again for your help, I really appreciate it!
