Thank you Andreas for your response. But unfortunately it does not resolve my problem totally. I am using PPPoE for Internet. If I am not connected to Internet and try to start the JBoss your suggestion works. But if I try to start JBoss after connecting to Internet same problem occurs. I have to set the hostname manually for the later. Any more clue..? Regards, Sahid View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4172241#...
