In the previous version of SBS, the Configure E-Mail and Internet Connection Wizard (CEICW) could be run again and again and again ... and again. If you had an issue with networking, you’d run the wizard as many times as you wanted to reset to the known SBS defaults. With 2008, we provided a wizard for exactly this case, called “Fix My Network” wizard.
The wizard is designed to detect known problems on your network, and then give you the option to fix them or not. There are roughly 70-80 different checks and fixes that it does. Some important things to note:
- The fixes may have dependencies. For example, if the wizard detects that the DHCP services are stopped, it will report that, but won’t be able to check the configuration inside the DHCP service, because it’s stopped. So, it’s important to run this wizard a few times, until you’re happy with the issues it’s finding/not finding.
- If you replace your router on your network, or change your router IP address, you should consider running the Connect to the Internet Wizard first.
- The wizard is designed to bring the network back to a “known good” working state. So any custom configuration will be un-done.
Now that you know how to use the wizard, what exactly are the things we keep an eye on? Well, to know exactly, you will have had to work on the wizard, but here is the high level.

A Common Question
Question: Does SBS support NIC Teaming?
Answer: The core OS supports it, but not the SBS wizards, it’s recommended you configure your network with a single network card, and then set up the team afterwards. Microsoft Support mentions they may ask you to disable the team for any troubleshooting.
