I have a laptop with Windows 7 and an older stationary with Windows XP. When I had a screen I set it up for use with remote desktop. I no longer have any screen, and used to connect to it using remote desktop, but that is a few years ago, and LAN details might have changed. When I connect the old computer to the network and boot it up, I cannot see it in the network browser, I don't know its name, its network group name or its IP address.
How can I sniff the network to discover it (should I use a cross-over cable directly?) and get back to using remote desktop?
