Config\MaxPollInterval

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

HKLM\SYSTEM\CurrentControlSet\Services\W32Time\Config

Data type Range Default value

REG_DWORD

 

15

Description

Specifies the longest interval (in units of 2n seconds, where n is the value of this entry) that is allowed for system polling. While the system does not request samples less frequently than this, a provider may refuse to produce samples when requested to do so.

Activation Method

To make changes to this entry effective, at the command line, type:

w32tm /config /update

Note

  • The time service itself is considered unsynchronized after 1.5 times the number of seconds specified by this entry have elapsed. The Network Time Protocol specifies that the maximum clock age is 86,400 seconds, so if the value of this entry is greater than 15, then peers will eventually ignore this server.

Caution

  • The default time providers installed in Windows Server 2003 do not synchronize at an interval greater than 1024 seconds.
