I have disabled all the  firewalls ,port and ip are ok too , i just realised that java dont work as it supposed to be working and it has

a problem .I  will reinstall and tell you the results...

I"m going twith nuumios first answer....connection refused usually is a fw issue....


Firewall blocking the connection would be my first guess. Have you tried any other connections between those PCs?

Second guess is that your client is trying to connect to wrong port and/or host.
