That's what they claim.

A google search on "iis kernel" brought up too many references to list.
However, the following was found at
http://www.infosecuritymag.com/2003/apr/lockdown.shtml:
----------------------
Finally, Microsoft made a major architectural change to IIS to improve its
performance. The logic responsible for initial processing of HTTP requests
was moved out of IIS, which runs in user mode, to a kernel-mode component
called http.sys. Code runs faster in kernel mode. But this could also be
disastrous if the code falls victim to a buffer overflow, since kernel mode
operates at a much higher privilege level. Microsoft is aware of the
increased security risk posed by http.sys, saying it has mitigated this risk
through extensive security testing, including threat modeling and
independent code reviews.
