First, a few questions: Was this a work computer or a home computer? In other words, was the computer connected to a business network, or to a network in a residence? Second, was it connected via Ethernet or wirelessly? If connected wirelessly, does the network you connected the computer to have a wireless segment that is able to communicate with the wired segment? Do you have a software firewall installed on the computer? (And no, Windows Firewall does not count)
