Thank you for your reply. I reviewed the link in your email and it looks like my server is configured with the proper entries in the hosts file and is using the correct ip protocol. I think that something is precluding JBoss from binding to the 8080 and other ports. Moreover, when I run JBoss4.2.3 instead of JBoss 5.0.0.GA, the server binds properly to the 8080 and 8443 ports but the shutdown scrit (shutdown.sh) freezes and I must kill the process to stop JBoss. I am getting the following warning and errors in the server.log file when I run JBoss5.0.0.GA with the script run.sh -b 0.0.0.0: [root@pbsiemr log]# cat server.log|grep WARN 2009-02-14 13:49:32,755 WARN [org.jboss.annotation.factory.AnnotationCreator] (main) No ClassLoader provided, using TCCL: org.jboss.managed.api.annotation.ManagementComponent [root@pbsiemr log]# cat server.log|grep ERROR 2009-02-14 13:49:33,412 ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] (main) Error installing to Create: name=TransactionManager state=Configured 2009-02-14 13:49:34,747 ERROR [org.jboss.system.server.profileservice.ProfileServiceBootstrap] (main) Failed to load profile: Summary of incomplete deployments (SEE PREVIOUS ERRORS FOR DETAILS): -> TransactionManager{Configured:**ERROR**} -> TransactionManager{Instantiated:**ERROR**} -> TransactionManager{Create:**ERROR**} -> TransactionManager{Configured:**ERROR**} *** CONTEXTS IN ERROR: Name -> Error TransactionManager -> **ERROR** | com.arjuna.ats.arjuna.exceptions.FatalError: [com.arjuna.ats.internal.arjuna.utils.SocketProcessId_2] - SocketProcessId.getpid could not get unique port.
