The server is a VMware server. The time was wrong so I manually changed the time. On the Windows 10 Pro Workstations that have joined the domain the time is wrong. When I try to change the setting manually. The message reads. ' some changes can't be made ' - I don't remember the official wording. We just took over this network. We even had Fortinet make the Firewall a NTP server. Even Fortinet support didn't understand this issue. We need someone to fix the time . I also want to push a group policy that makes the workstation lock screen the school logo with a screen saver. IT's a busy time and I just need to pass this on to someone.
