The computer did not resync because the required time change was too big

May 24, 2008 · 5 Comments

Microsoft Windows Vista has a built-in feature to synchronize your machine’s time automatically with global time servers around the world. The service can be scheduled to run automatically and works like charm keeping your system time up-to date, but there’s a tiny catch in here.

If your computer’s clock is async for more than 15 hours, this service will not work for you saying “An error occurred”.

Copy the following code and save it as .reg file, apply it and re-run the synchronization. It will work !

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config]
"MaxNegPhaseCorrection"=dword:ffffffff
"MaxPosPhaseCorrection"=dword:ffffffff

The above code is also available in pastie @ http://pastie.caboo.se/179732.

Thank you, thank you!

I had a problem with time synchronisation after my CMOS reset. Manually changing the time did nothing, and it still wouldn’t synchronize despite seemingly being within 15 hours of the system/Internet time.

This worked for me, and has saved me a great deal of trouble.

Thank you again!

Thank you very much! The only comment that time service should be restarted in order this hack will start working
