I recently purchased 2 laptops that came preinstalled with Windows Vista Home Premnium, and I have trying to set up a network through my desktop which is running Windows XP. I was succesful in establishing an internet connection through a router for the laptops, but I have not been able to establish any real network connection between the 3 devices. I believe the main problem may be that the devices are on different OS and are having trouble “finding” each other. Is there any way to resolve this issue without “upgrading” my desktops OS?
