We had some problem with the Windows Time Service a while ago. It was set to 'manual' startup and was not started. We set this to 'automatic' startup on every server and configured it properly to sync with the domain controller.
Today, we have one server that fell back from 'automatic' startup to 'manual'. And it stopped. What is the possible reason for this? It was unable to contact the domain controller?
I could not find anything in the logs about this configuration switch...
