Can any one please help me to resolve this time syncronization issue. I have 2 Windows 2008 servers which we want to change the time zone to eastern but every time we reboot the time zone comes back to the default zone (Mountain Time). Can you please help me to fix this problem.

As far as I know there really is no default. Before reboot I'd check that it is being written properly. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation After change move out of TimeZoneInformation folder and back to see effect. Regards, Dave Patrick ....

Hello, Have you also checked the BIOS time and make sure the time is correct? What if you disable "Synchronize with an Internet time server" option in internet Time tab and check the result after a reboot. If these are two Hyper-v virtual machines, are they configured to sync time with the host?
