How To Install Ntp Server On Windows 2008 R2

How to prepare Internet time on Windows Server 2008 R2

To configure an internal time server to synchronize with an external time source, follow these steps:

Change the server type to NTP. To do this, follow these steps:
1. ClickStart, clickRun, type regedit, and and so clickOK.
2. Locate and and then click the following registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
  \Services\W32Time\Parameters\Type
3. In the pane on the right, right-clickType, and then clickModify.
4. InEdit Value, blazon NTP in theValue data box, and so clickOK.
Gear up
AnnounceFlags

to 5. To do this, follow these steps:
1. Locate and then click the post-obit registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
  \Services\W32Time\Config\AnnounceFlags
2. In the pane on the right, right-clickAnnounceFlags, and so clickChange.
3. InEdit DWORD Value, type 5 in theValue data box, and then clickOK.
  
  Notes
  - If an authoritative time server that is configured to use an AnnounceFlag value of 0x5 does not synchronize with an upstream time server, a client server may not correctly synchronize with the administrative time server when the time synchronization between the administrative time server and the upstream time server resumes. Therefore, if you take a poor network connection or other concerns that may cause time synchronization failure of the authoritative server to an upstream server, set the AnnounceFlag value to 0xA instead of to 0x5.
  - If an authoritative time server that is configured to utilise an AnnounceFlag value of 0x5 and to synchronize with an upstream time server at a fixed interval that is specified in SpecialPollInterval, a client server may non correctly synchronize with the authoritative time server subsequently the administrative time server restarts. Therefore, if you configure your authoritative time server to synchronize with an upstream NTP server at a fixed interval that is specified in SpecialPollInterval, set the AnnounceFlag value to 0xA instead of 0x5.
Enable NTPServer. To practise this, follow these steps:
1. Locate and then click the following registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
  \Services\W32Time\TimeProviders\NtpServer
2. In the pane on the correct, right-clickEnabled, and so clickAlter.
3. InEdit DWORD Value, blazon ane in theValue information box, then clickOK.
Specify the time sources. To do this, follow these steps:
1. Locate and so click the following registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
  \Services\W32Time\Parameters
2. In the pane on the right, right-clickNtpServer, and then clickChange.
3. InEdit Value, typePeers in theValue data box, and then clickOK.
  
  Note Peers is a placeholder for a space-delimited list of peers from which your figurer obtains time stamps. Each DNS name that is listed must be unique. Y'all must append ,0x1 to the finish of each DNS proper name. If you do not append ,0x1 to the cease of each DNS name, the changes that you brand in step 5 will not take result.
Select the poll interval. To do this, follow these steps:
1. Locate and then click the post-obit registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
  \Services\W32Time\TimeProviders\NtpClient\SpecialPollInterval
2. In the pane on the right, correct-clickSpecialPollInterval, and then clickModify.
3. InEdit DWORD Value, typeTimeInSeconds in theValue information box, and and then clickOK.
  
  Note TimeInSeconds is a placeholder for the number of seconds that y'all want between each poll. A recommended value is 900 Decimal. This value configures the Time Server to poll every 15 minutes.
Configure the time correction settings. To do this, follow these steps:
1. Locate so click the following registry subkey:
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet
  \Services\W32Time\Config\MaxPosPhaseCorrection
2. In the pane on the correct, right-clickMaxPosPhaseCorrection, and and so clickModify.
3. InEdit DWORD Value, click to selectDecimal in theBase of operations box.
4. InEdit DWORD Value, typeTimeInSeconds in theValue data box, and then clickOK.
  
  Annotation TimeInSeconds is a placeholder for a reasonable value, such as one hour (3600) or 30 minutes (1800). The value that you select will depend on the poll interval, network condition, and external time source.
5. Locate and then click the following registry subkey:
  HKEY_LOCAL_MACHINE\System\CurrentControlSet
  \Services\W32Time\Config\MaxNegPhaseCorrection
6. In the pane on the correct, right-clickMaxNegPhaseCorrection, so clickAlter.
7. InEdit DWORD Value, click to selectDecimal in theBase box.
8. InEdit DWORD Value, typeTimeInSeconds in theValue data box, and then clickOK.
  
  Note TimeInSeconds is a placeholder for a reasonable value, such equally 1 60 minutes (3600) or 30 minutes (1800). The value that you select will depend on the poll interval, network condition, and external time source.
Close Registry Editor.
At the control prompt, type the following command to restart the Windows Time service, and and so press Enter:
cyberspace stop w32time && net start w32time
