Ok. Things to check;

1) Is the machine definitely called ‘main’? Check this by opening Command Prompt and typing HOSTNAME and then enter. This will display you the name of the machine

2) check the firewall again

3) check that your laptop is trying to connect using the right IP address for main. On main, open Command Prompt and type IPCONFIG and the enter. Make note of the IPv4 address. Then on Laptop, open Command Prompt and type PING MAIN and make note of the IP address it tries to contact. If it shows nothing or the wrong IP, then type PING followed by the IP address you took note of on MAIN and check the result.
