The can have troubles with starting java with MBeans server authentication under Windows XP Home.

http://java.sun.com/j2se/1.5.0/docs/guide/management/security-windows.html document doesn't describe how to set permissions in Home Edition of the Windows XP system. There is no 'Security' tab and no 'Use simple file sharing' Option in View tab of Folder Options. The permissions can still be modified as described in http://whoozoo.co.uk/winxpFilePerms.htm#4.
