Hi,
Please check at os level if the port 3351 is listening or not
You can use below commad
netstat -An|grep -i 3351 .If port is listening it will return a value
If not you need to contact your OS admin to open the port
can you check /etc/hosts file and see if entry d51.sonyericsson.net is maintained .
If not edit it and place below details
<IP of the d51.sonyericsson.net server> FQDN(d51.sonyericsson.net)
Regards,
Murali
