I found internat.exe, can you

I reinstall the IIS, and select only Com Files，IIS Snap-In，WWW Server, and PWS options only.
I did find internat.exe, can you tell me if it's working or not?
Here is what it says:
Image Name PID CPU CPU Time Mem Usage
internat.exe 1436 00 0:00:00 1,376 K

Can you tell me how to set up IIS Admm Service property also ?
General=? Log On=?
I still can't run ASP, http://localhost/ gives "The page can't be displayed".
It's for my personal study only.
Thank you so much.
