How To Configure A Windows Server Or Windows System As A Network Time Server (NTP)

If you can’t allow your Room Alert Monitor to access a time server through the Internet, and you don’t have one available on your network, you may configure a system running Windows (XP and above) or Windows Server (2003 and above) as a time server. The Room Alert Monitor can then use this system to obtain the date and time.

You’ll use the Windows Time service, which is in the system’s Service list.

– The application executable is ‘w32time.exe’.

– You may find the w32time parameter list in the Windows Registry at this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time

Make the following Registry changes in the Windows Registry. Be aware, however, that serious problems could occur if you modify the registry incorrectly; these problems could require you to reinstall your operating system. Modify the Registry at your own risk!

Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\Type
Value: NTP

Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config\AnnounceFlags
Value: 5

Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NTPClient\SpecialPollInterval
Value: 900

Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NTPServer\Enabled
Value: 1

Key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\NtpServer
Value: NTP server IP addresses or DNS names, separated by a space
