on 15 July 2018 I installed the following updates: KB4338815, KB4054566, KB890830. These were standard updates applied by checking for updates with Windows Update.
Since these were applied, IISRESET no longer works. The "Attempting Stop..." phase takes a long time (seems to time out without a message), and "Attempting Start..." times out and gives this error:
The service did not respond to the start or control request in a timely fashion. (2147943453, 8007041d)
It looks like at least one other person on the planet is seeing this (see link below).
I am also seeing this issue. We have KB4338815, KB4054566 installed and this only started happening within the last couple of weeks.
Brian, did you ever find a solution for it?
We are also experiencing this issue.
Update: I simply rolled back the July Updates and iisreset is working again.
