We have a windows 2008 R2 domain with a physical domain controller server(HP DL380) acting as ntp role for the domain. This is setup to sync externally with,,,,
Recently the date and time jumped ahead just over 2 weeks causing various problems, mainly stopping users logging on and kicking existing users off the network. The only way I could fix the problem was by manually setting the time back and then running the command to test and auto update time sync which worked fine once the date/time was set back within the 2 week limit.
My concern is I still do not know what caused the date/time to change, I have checked event viewer etc and can see the date time changed gradually within a couple of hours.

I contacted and they confirmed no issues and also confirmed not heard of before so I am left puzzled and concerned that this could happen again at any time but more importantly i need to know what the root cause was.
any help appreciated, also I am aware similar issue can happen in virtual servers with host etc but my server is physical.
