Installation guide

4. To enable the NTPServer, in the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\
NtpServer\Enabled subkey, change the REG_DWORD value to 1.
5. To specify where the computer obtains time stamps, in the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\
NtpServer subkey, enter the list of DNS names or IP addresses.
If you use DNS names, append ,0x1 to the end of each DNS name.
6. To set the poll interval, in the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\
NtpClient\SpecialPollInterval subkey, change the REG_DWORD value to the number of
seconds between each poll.
The recommended value is 900 Base Decimal, which polls the time server every 15 minutes.
7. To specify the maximum positive difference that triggers a synchronization, in the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\
MaxPosPhaseCorrection subkey, change the REG_DWORD value to the maximum number
of seconds.
The recommended value is 3600 Base Decimal.
8. Similarly, to specify the maximum negative difference that triggers a synchronization, in the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\
MaxNegPhaseCorrection subkey, change the REG_DWORD value to the maximum number
of seconds.
9. Exit the Registry Editor.
10.
To stop and restart the Windows Time server, at a command prompt, type net stop w32time
&& net start w32time.
It may take up to an hour for this to take effect.

Synchronizing Windows servers to an internal time source
(Topic number: 58720)
Synchronize the Windows Server 2008 R2 servers on your network to ensure that image data streaming
operates correctly. To configure the Primary Domain Controller (PDC) master without using an
external time source, change the announce flag on the PDC master. Choose either the Application
Server or the AS300 server as the PDC master and sync the other servers to it.
CAUTION!
Serious problems might occur if you modify the registry incorrectly. These problems might
require that you reinstall your operating system and we cannot guarantee that these problems
can be solved.
