It has happened to me in a couple of Win32 installations that a fresh new install fails to startup properly with the given error:
15:29:02,468 WARN [ServiceController] Problem starting service jboss:service=invoker,type=http java.net.UnknownHostException: DS-SW-0001: DS-SW-0001 at java.net.InetAddress.getLocalHost(InetAddress.java:1308)
127.0.0.1 localhost 127.0.0.1 DS-SW-0001
JAVA_OPTS="-server -Xms128m -Xmx128m -Djava.rmi.server.useLocalHostname=false -Djava.rmi.server.hostname=127.0.0.1"
Try adding -Djava.net.preferIPv4Stack=true to JAVA_OPTS and see if that helps. I had a similar problem, though on Fedora Core 4 with the Sun JVM 1.4.2_10, and setting that option fixed the problem.
