256986 Description of the Microsoft Windows Registry
SYMPTOMS
If you restore a system to different hardware, the system may start to lose time when Windows tries to synchronize the time by using the Windows Time service. This issue may also occur if you use images to install Windows 2000 on a different hardware architecture.
CAUSE
The Windows Time service uses a clock rate that depends on the time interrupt rate, which can be different based on the hardware. In Windows 2000, the Windows Time service stores this information in the following registry location:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\W32Time\Parameters\Adj
The Adj value varies by hardware. If you use images or restore to different hardware, the Adj rate cause the system not to synchronize correctly.
WORKAROUNDWARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.
To work around this problem, delete the Adj value from the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\W32Time\Parameters
After you stop and then restart the Windows Time service, the system time functions correctly.
