Hi i dont kno if anyone can help me but im trying to set up LAN. I want to be able to have a IP address for every computer but not have to do it to all something so  you could just PLUG a network cable into a computer and it would have a IP address sent to it and it needs to beable to work with WORKGROUP. i have seen it done before and now i would really like to know how to do it. if you can that would be great.
thanks in advance.If you know any thing a bout computers , Set Up ICS on one computer , and it will give all your computer IP's that will work together if there set to auto configure.

if you dont know how to do that ill give you step by step instructions" I want to be able to have a IP address for every computer but not have to do it to all something so "

I am not sure what this sentence mean, can you clerify it?

Also it would be helpful if you can provide more INFO on what OS you use on your network, number of PCs etc...

" I want to be able to have a IP address for every computer but not have to do it to all something so "

by that i mean not having to go to all the individual computers and change the IP address

Im running XP pro and so are all the other computersOh yes, do you have a router? if not not you can use ICS as suggested but a hardware router WORKS better. And if you want static IP address for each PC you can disable the DHCP server from your router and assign IP address to each PC via the TCP/IP control panel. (I am assumming you use Windows.)  But becareful, make sure you use the correct IP range and the subnet mask. Write back if you don't already know how to do this.The Easyiest way is to set Up a DHCP, and windows XP has one built in to  ICS, it will do what you want, im going on lunch now , when i get back i type up how you can do it , its prety simple , and will be easyest if one of your computers has 2 network connections.thanks heaps. ill give it a go.Also refer to the >home networking FAQ<.How to Set up a Simple Network,

Frist Pick A master PC, most people st up net works to share some thing like files or INTERNET connection, i would use my pc that has the internet conection.

Then click properties, and go to the "advanced" tab, you should see a box called "Internet Connection Sharing"

Check that box and click ok if it gives you a promt click yes or ok, then click ok in the Properties window.
