I don't understand this comment at all. Ideally IIS should be running as
an unpriviledged user, like in the good ole IIS 3 days. Back then the
service was running under a user account so even if the IIS service got
hijacked through a BO, you still had to hack your way to privileges. No
immediate SYSTEM there.

The reason IIS4+ runs as SYSTEM appears to be to gain performance. I
guess running IIS as a kernel module and having less context switches
does do well for performance (like an Apache LKM), but unfortunately not
for security.

What specific kernel task were you referring to?

Frank
