I just now verified correct operation on XP SP2 using Native 2.0.4, AS 4.2.3, JDK 6u7. Is the shutdown orderly, or does the system just suddenly power off? Post the settings for the System and Recovery properties, in the System Failure area. Also, get the listdlls utility from sysinternals. With jbossas running, open a command prompt and enter: listdlls java Post the results that pertain to jbossas. As do: listdlls jbosssvc and post those results. The listdlls output will let us know if there is an unusual DLL that got loaded into the JVMs address space.
