Here is a test class which reproduces the problem: import java.util.Properties; import javax.naming.Context; import javax.naming.InitialContext; import javax.naming.NamingException; public class ContextTest {   public static void main(String[] args) {     String url = "localhost:1099";     // String url = "AHRC00WKG2208:1099";     Properties p = new Properties();     p.setProperty(Context.INITIAL_CONTEXT_FACTORY,         "org.jnp.interfaces.NamingContextFactory");     p.setProperty(Context.URL_PKG_PREFIXES,         "org.jboss.naming:org.jnp.interfaces");     p.setProperty(Context.PROVIDER_URL, url);     try {       InitialContext context = new InitialContext(p);       Object queue = context.lookup("queue/ImageUploadQueue");       System.out.println(queue);     }     catch (NamingException e) {       e.printStackTrace();     }   } } When I run this against JBoss 4.0.3, either url will work, but against 5.1.0, running against the non-localhost value causes the following exception: javax.naming.CommunicationException: Could not obtain connection to any of these urls: AHRC00WKG2208:1099 and discovery failed with error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out] [Root exception is javax.naming.CommunicationException: Failed to connect to server AHRC00WKG2208/143.134.34.36:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server AHRC00WKG2208/143.134.34.36:1099 [Root exception is java.net.ConnectException: Connection refused: connect]]]     at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1763)     at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:693)     at org.jnp.interfaces.NamingContext.lookup(NamingContext.java:686)     at javax.naming.InitialContext.lookup(InitialContext.java:392)     at com.tauman.test.ContextTest.main(ContextTest.java:24) Caused by: javax.naming.CommunicationException: Failed to connect to server AHRC00WKG2208/143.134.34.36:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server AHRC00WKG2208/143.134.34.36:1099 [Root exception is java.net.ConnectException: Connection refused: connect]]     at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:335)     at org.jnp.interfaces.NamingContext.checkRef(NamingContext.java:1734)     ... 4 more Caused by: javax.naming.ServiceUnavailableException: Failed to connect to server AHRC00WKG2208/143.134.34.36:1099 [Root exception is java.net.ConnectException: Connection refused: connect]     at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:305)     ... 5 more Caused by: java.net.ConnectException: Connection refused: connect     at java.net.PlainSocketImpl.socketConnect(Native Method)     at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333)     at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195)     at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:182)     at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366)     at java.net.Socket.connect(Socket.java:519)     at org.jnp.interfaces.TimedSocketFactory.createSocket(TimedSocketFactory.java:97)     at org.jnp.interfaces.TimedSocketFactory.createSocket(TimedSocketFactory.java:82)     at org.jnp.interfaces.NamingContext.getServer(NamingContext.java:301)     ... 5 more I'm sure that there is something simple I am missing, but for the life of me, I can't figure it out. Any help would be greatly appreciated.
