I encountered it once in the middle of the night. Later, I thought there was something wrong, so I didn't find it out, so I restored all the sites and used them for more than half an hour. Because it was 0 o'clock, there was basically no user feedback. This problem occurred again this morning, of course I can't use the first half of the hour to deal with it.
Look at the management tools - 》 Local security strategy - 》 Account password. Is there a password that takes 49 days? Change it to a longer time.
When I entered, I found that it was true that changing to 0 would never expire.
This problem is relatively rare. Generally, virtual host management software is automatically set.
