In SBS 2003, the CEICW was available to administrators for configuring their firewall, Internet connection, self-signed certificate, and email settings from a single wizard. Re-running the CEICW was a common troubleshooting step in fixing network related problems. However, SBS 2008 has taken the concept of the CEICW and broken it down into several specific wizards in place of one monolithic wizard. Administrators can now address more specific tasks, reducing the likelihood that they may inadvertently change settings that are unrelated to their end goal.
One of these new wizards is the FNCW, which is solely a troubleshooting tool meant to help the administrator resolve network issues. It automatically scans the environment for potential issues with Certificate Services, certificates, DNS, DHCP, TCP/IP configuration, VPN, Exchange, IIS, and Network Discovery. It will either attempt to correct them automatically, or will suggest a course of action to take towards resolution.
