Server Time Keeps Changing to 2 Hours in the Future
We have a Windows server that is part of a domain. The server's time keeps changing to two hours in the future. We have a large domain with many other servers that are not having issues.
I have unregistered w32time and re-registered it.
Edit: This is a Virtual Machine (VMware) and Host Time Synchronization is not enabled.
