And there might be something useful for you in this lot...

You might want to rename the computer you choose to something easy because
the website address will be \\computername unless you use it's IP address
which will be something like 192.168.0.5 although if you set the homepage on
each client machine or put a shortcut on the desktop I guess that won't
matter much.
From the machine you choose to install PWS on the address
http://127.0.0.1
should work for test purposes or
http://localhost if I remember correctly.
You probably don't want to use PWS with an internet connected network unless
you have a firewall but it should work on a LAN if that's all you need.
Hope this helps a bit, but if you plan to go on to internet servers you will
either have to go with Linux and something like Apache or Windows 2000
"Server" editions to use their built in IIS servers. Of course you can get
Apache for Windows too and Windows server 2003 is behaving very well here on
test but it has more trouble with older hardware than 2000 server (finding
the right drivers etc).
