How do I setup a home network using xp pro and a linksys router?

I have 4 computers, 3 using XP Pro, 1 using Vista. I have cable internet, which is connected directly to my Linksys router model # BEFW11S4. Internet works great on all of the computers. 2 of the computers have a wireless connection to the router (1 of the XPs and the VISTA), and the other 2 are connected via Ethernet cords. I just want to be able to share a printer (if fairly easy to setup), and files between all the computers. I tried running the network wizard, made a network setup file, put it in the wireless XP computer and it told me the computer already belongs to a domain?? Please help.|||In order for you to share them all, you have to make them all part of a "workgroup" you are not in a "domain" that is if you had a server running windows server software. On the XP: Right click on my computer click on the computer name tab, click on where it says "To rename the computer or join a domain click Change" You can name your computer whatever you want, maybe leave the name like it is already, since you know what each one does or belongs to, but go to where it says member of: click on workgroup, and make up a group name it doesn't matter what it is, as long as it is short an simple, something that identifies your home network. then restart the PC. do this for all the PC's.


In the Vista computer, is about the same, except after you click on properties in the computer, click on the left where it says: Advanced system settings, then click on the computer name tab and click on "to rename this computer click change".


You might have to turn off firewalls, because the Vista has a security issue trusting other computers. Good luck.
