I have four computers, 3 with xp and 1 with vista, all using the same wireless router for access to the Internet. Is there a way that I can set up all these computers to have full access to a folder saved on one of the computers hard drive?
Just run the network wizards on all the machines. The place you may have problems with is being able to access data from the vista machine. Just some quick tips. Make sure when you set files up to share that you give access to both read and write. When setting up sharing in Vista make sure to select share with everyone to share over the network.
