As Hugh suggests, Vista will be the oddball. There is some code in Vista which was NOT backward compatible unless you load a special patch on the XP machines (SP2 and newer only), otherwise the older OS's won't be able to see the Vista computer. Make sure they are all on the same work group. I would start building with the wired XP Pro system. If you don't have something shared on each computer you may overlook that machine by accident. I started my network with two computers and have just added and subtracted from there. I was working on one network in which there was 1 XP-SP2 pro machine and 2 Vista. The printers were locally connected to the XP machine. The only way I could get all three to see each other was to load the network patch and then create an administrator level account with the same password on each machine; access the other machines and "remember" the account and password. Even then, there are times when the user must enter a password before accessing shared files or a printer. The newer the OS, the more likely it is that that machine will force an election to become the "browse master" (a background service necessary for peer to peer networking). Since Vista is the newest and won't work with your XP-SP1 or 98 machines, I suggest the Vista machine be added to a different workgroup. You will also want to try to keep the browse master on a wired machine or the network may slow down by looking to a wireless computer for that service. You can Google "browse master" for more information. Ron Jobe On Wed, Jul 15, 2009 at 5:04 PM, Bob Lendrim <[log in to unmask]> wrote: > I'd like to make a network at my home.
