If I am reading your question correctly, I would imagine it is because the computer is not on the same network...
**The computer has an invalid default gateway address**
This is usually used to describe the Internet. A few computers connected together is a computer network. A few computer networks connected together is a network of networks.
Computer network : A collection of computing devices that are connected in various ways in order to communicate and share resource. Usually, the connections between computers in a network are made using physical wires or cables.

Computer network.
There are millions of types of different networks in the world. These networks may be as simple as a computer network for example.
Computer Network is all about sharing Information & Resources amongst Users & Devices within network. Computer Networks enables efficient usage of Resources (Such as printers, scanners etc) so that multiple devices for same functionality aren't required at every user's place. Computer Networks can provide Central Stored information & makes them available to all permitted Network users or devices.
Two types of computer networks are LAN (Local Area Network), which connects devices within a small geographic area like an office or building, and WAN (Wide Area Network), which connects devices over a larger geographic area, such as across cities or countries.
