I found 2 kb for this problem. One talk about the service account (VMware KB: VMware vCenter Storage Monitoring Service fails with the error: Service initialization failed after upgra…)
Another alk about H2 database that may be corrupted (VMware KB: VMware vCenter Server Storage Monitoring Service fails to start ). This second kb indicate that delete the file in sms directory in "C:\Program Files\VMware\Infrastructure\tomcat\webapps" but i don't have sms directory here. May be it is a start of search to my problem.
Have you an idea ?
