Check in Device Manager, does it show your NIC? Does it show an exclamation point?
If it doesn't appear, you need to install it. If it has an exclamation point, you need to get that repaired so it works properly.
If your NIC is working, can you ping the other computers? Does yours have the same workgroup name as the rest?
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
