it is done but still it is not showing..

What is the OS?  What is the session the service is running in ?
For post-Vista OS your service is running in session 0 and then, since the application cannot run in session 0, are we sure that there is no issue here ?

OS is xp & win 2003

console application now started executing but only sometimes... means 1 outof 5 time console app execute..

what is this issue..?

No I am not closing the question... I have accepted the multiple solution..
