rmiexception while starting glassfish server - glassfish

Question

I have the glassfish server and I am trying to run the server from netbeans. I am getting the following errors:
WARNING: Cannot start JMX connector JmxConnector config: { name = system, Protocol = rmi_jrmp, Address = 0.0.0.0, Port = 8686, AcceptAll = false, AuthRealmName = admin-realm, SecurityEnabled = false} due to exception java.io.IOException: Cannot bind to URL [rmi://MAZUMDAM4.americas.hpqcorp.net:8686/jmxrmi]: javax.naming.ServiceUnavailableException [Root exception is java.rmi.ConnectException: Connection refused to host: MAZUMDAM4.americas.hpqcorp.net; nested exception is:

Now after searching google I came across various suggestions.
a. Checking the firewall. The firewall is not an issue. Because this was working fine just two days ago and it stopped suddenly.
b. Setting the JMX port from the admin console. I did it and it didn't work.
c. Checking the port to see whether it is already used. I checked it. Moreover, I restarted the glassfish server. Even restarted the computer. Nothing changed.
Now I need the help of some wise guys to give some clue in resolving this.
Thanks

Answer 1

start up the domain, get into the admin console.
In the admin console, navigate
Configurations > server-config > AdminService
There is a tab in the main window that is titled "Edit JMX Connector"
The IP address is probably set to "0.0.0.0" (all IP's)
change that to "127.0.0.1"
you MIGHT also need to add an entry in your hosts file
for the domain name in the errror
"mymachine.SOMEDomain.net" or whatever.. so that it resolves to 127.0.0.1.

The underlying problem is
Caused by: java.rmi.ConnectException: Connection refused to host: MAZUMDAM4.americas.hpqcorp.net; nested exception is:
java.net.ConnectException: Connection timed out: connect
during rebind(). See the stack trace. RMI is getting no response at all from that host when attempting to bind a remote object to its Registry. This is a network topology problem or possibly a DNS problem. It should be trying to bind to a registry at 'localhost' only.
