Thanks Leif,
I think we'll split the application and run them as two processes.
Thanks,
Aparna

Aparna,
Not that I know of. Some applications get around this problem by
running two processes. One is the main service process, and the second
is a small process that gets launched when a user logs in. It runs as
the logged in user and communicates in the background with the main
service using a state file, socket, or some other method.
I know it is a pain, but I am not aware of any way to get around
this due to the way Windows is designed.
If anyone has any other information on this, I would love to hear
about it as well.
Cheers,
Leif
