error : Can’t start service W3SVC on computer ‘.’. Dynamics 365 for finance and operations.

I got error on My Dev box virtual machine. When I tried to restart AOS or IIS service.

I found that World wide web service is in stopping mode. Some reason it stuck. So I restart my machine.

AOS/ IIS works perfectly fine after restart. Basically two services need to run if you found this error

• IIS admin service.
•  World wide web service
