Currently, there are two servers used for Exchange mail, Fangorn and Rivendell. You may get this error message when your Exchange account is on a different Exchange server than the person (or resource account) whose inbox or calendar you are trying to access. Therefore, your computer is unable to resolve what it considers to be an unqualified server name.

1. Configure your WINS server settings. For instructions, refer to Configuring WINS Settings in Windows XP/Vista/7 (http://answers.vt.edu/kb/entry/1316/).
   Important: If you are running a third-party firewall, such as Integrity Desktop, you must add the Virginia Tech Exchange servers' IP addresses, including the WINS server addresses, to your trusted zone list. For instructions, refer to Cannot Connect to the Virginia Tech Exchange Server While Running Integrity Desktop (http://answers.vt.edu/kb/entry/2782/).

2. If you continue to receive this error message after configuring your WINS server settings, edit your hosts file to include both Virginia Tech Exchange servers' IP addresses.
