Service Logon Account

Hi,

I have a Service , which runs in the "LocalSytem" Service logon
Account in any OS(xp\2000\2003) . Now I am running the same
application(Service ) on Windows Vista, it is not running with the
LocalSytem service logon account. If I run with the "Administrator" service
logon account and the password of the same it works fine . please can
anybody help me to make the service running with the "LocalSystem" service
logon account.


NOTE: My application uses the WMI interface , and it will execute some WMI
methods .

Can any body tell what is the WMI Access policy for vista


Thanks in advance,
ajay
