SSH - Connection Refused

[cheaterpumpkineater]

Hello. I just got my new LAN turtle and I've been having some problems with Windows not installing the right drivers. Luckily I got that fixed. However, after updating and installing all the modules on to it, indecided to go ahead and ssh into it using its network ip address and putty. I could do this from the host computer but when I tried from a computer on the same network, I can't connect (connection refused).

Any ideas on what's going on and how I can fix it?

Thanks
