Vista's Control Panel Home view and Network and Sharing Centre might confuse it a bit, but it's effectively in the same place, the Computer Name tab of the System Properties control panel.the machines on xp are set to the same workgroup but i cant for the life of me find anywhere in vista to set it to the same?
Disable the 3G connection and try it. You'll probably find it works when the 3G connection is enabled and online, but not when it's enabled and offline, because Vista can't establish the type of network it's connected to when a connection is offline. Dunno if there's a better way around it.also have you any idea why i cant set the network to private on the vista machine or should that not really be an issue>?
