Thank you ,Karl
I found the package,details on :
http://support.microsoft.com/default.aspx/kb/931836Now I have a new issue need your help.
I set up my win2003 server as a NTP server
With regedit set w32time parameters:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type "NTP"
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\AnnounceFlags "5" (decimal)
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer\Enable 1
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\NtpServer "IP,0x1"
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\LocalClockDispersion "0"
Then I restart w32time service and sync my debian system to this win2003 server.
It is successfully.
Then, I changed win2003 server time back 2 min. leave my debian running, after 2 days, time does not synched.
The offset is increasing...
If you need more info, i will update for you.
Best wishes
