SBS 2008 Knowledge Sharing series

If you are a MS partner, going into the Managed newsgroups every now and then means you find stuff like this:



This is the third round of this SBS 2008 Knowledge Sharing series.
Continuing with our last topic, this time we would like to introduce another
important networking wizard called Fix My Network Wizard (FNCW).

FNCW 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.
The FNCW has been designed to be run by the administrator as the first step
in any network related troubleshooting. You can launch it as many times as
you require from the Windows SBS Console under the Network > Connectivity
sub-tab.

After it performs its initial scan, it will display a list of issues that
require your attention.

Once you click “Next”, it will attempt to fix the issues automatically. If
it is unable to do this, it will suggest a course of action to be taken by
the administrator. This may involve running one of the other SBS 2008
wizards, performing manual configurations, verifying the state of underlying
components, or performing deeper technical troubleshooting.

If the wizard is able to fix the issue, it will require no further action
from you for that specific item.

There are roughly 70-80 different checks and fixes that it does.  Some
important things to note:

1. 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.

2. 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.

3. 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.
