Then, open a Command
Prompt window and type nslookup ip_address, where ip_address is the
set of four numbers reported by Annoyances.org. This should give you
the name of your ISP, plus some extra stuff. So, you might see something
like dsl456.eastcoast.superisp.net, which means your ISP is
superisp.net. Then, it??™s only a matter of visiting the ISP??™s web site (e.g.,
http://www.superisp.net/) and determining its DNS server addresses from
its online documentation.
7. Click OK in both boxes when you??™re done.
These static IP numbers, provided you??™ve typed them correctly, will help
ensure that all the PCs on your network can communicate reliably with one
another. You don??™t have to set static IP addresses on all the PCs on your network,
but it may help settle a cranky network, particularly one with computers
running several different operating systems (Linux, Mac OS X, older
versions of Windows, etc.).
Return to the Network Connections window when you??™re done, and look at
the Status column entry for the connection you??™ve just modified. If it says
Acquiring network address, it means Windows is in the process of establishing
a connection; if you see this for more than, say, 10 seconds, you??™ve probably
done something wrong. If the status is Limited or no connectivity, it
means that a connection has been established, but your IP address is incorrect.
If, at this point, your network appears to be functioning, you can proceed to set
up the various services you need, such as file and printer sharing (described in
Chapter 8) and Internet Connection Sharing (described later in this chapter).
