Re: Boot sequence?

Hi,
1. Just some clarity in terms. A "Service" is a application running in the
"Background as a PROCESS?"

2. It sounds like that a SERVICE can start in the boot up sequence of the
Operating System and not require a User/Administrator to login?

3. It also sounds like that a Service needs to be first installed at the
Administation level before it can operate?

Thank for your assistance,

MDW
