What you bought is the NASLite FDU CD. It provides a simple way for windows users to create the floppies for the free version of NASLite, which are a non-standard larger format to allow as much program as possible to fit. So you paid $19.99 for a program to make the free floppy version of NASLite. You can make as many copies of the free floppies as you want and install them on as many machines as you want.
The NASLite+ or NASLite + for USB flash are $24.95 and boot from a CD or USB memory stick so there is room for the full set of features. You can only install the NASLite+ versions on one machine.
For the docs go here:
http://www.serverelements.com/naslite.php and go to the bottom of the page where there is a section titled "Getting NASLite v1.x" and a table.
Click in the icon with an
i in it on the SMB row in the table. (2nd icon in from the right)
This will open an Adobe Acrobat window to view the documents, so you must already have Acrobat installed for it to work. Go to
http://www.adobe.com and get the free Acrobat reader if you don't have it already. I was able to download the docs very quickly. They're about 350k in size.
To help you with your IP address question we would need to know what your network is set up as. Is it a home network with just one XP machine and some sort of router to connect to DSL or cable? Or do you have multiple machines? Is it using DHCP or static IP addresses?
To find out what IP address your XP machine is using now click Start->Control Panel and then double click on Network and Internet Connections, then double click on Network Connections, then double click your LAN or High Speed Internet connection to bring up a status box. Click on the Support tab at the top to see what your XP machine's IP address and Default Gateway (router/cable modem) IP address are and the Address Type. If the Address Type says Manually Configured you have a static IP address. This means the IP address will stay the same even if you reboot. If it says something like Automatically Assigned then you are using DHCP and getting an IP address from the router/cable modem which could change every time you reboot. Write down the IP address and default gateway address. If you have other XP computers on this network, do the above for them as well to get their IP addresses. This will tell you what IP addresses are being used at the moment. I don't remember if you need the Subnet Mask numbers, but write them down just in case.
Assuming you have a home network with one router/cable modem and one PC which is assigned an IP address by the router, you can assign the NASLite box any IP address not being used.
If they are in the 192.168.1.xxx range then all you have to do on the NASLite box is configure the IP address to be 192.168.1.xxx where xxx is a number between 1 and 254 and different from the IP address of your router and any other computers on the network. I would also try to make it a number that is far away from the other IP addresses to avoid possible conflicts with future DHCP assignments.
For example, if your computer was 192.168.1.2 and the router was 192.168.1.1, I would make the NASLite IP address 192.168.1.200
Generally the first 3 numbers in the IP address will be the same, so all you have to do is pick the last number.
Don't forget to save changes and reboot to apply them.
