Increase NTP Frequency

cxls

Hi,

Is there a way to make my pfSense box check pool.ntp.org more frequently to synchronize time? Currently it works, but after a while computers behind the firewall won't accept it as a valid source of time since it hasn't updated recently enough.

Also, is there a setting in Windows to change how often it checks the specified server for time updates?

I ask because I have a laptop that keeps horrible time.

Thanks.

For Windows 2000 and XP, try this (at Table 6) http://www.microsoft.com/windows2000/docs/wintimeserv.doc

For other Windows… ? Perhaps here: http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/security/ws03mngd/26_s3wts.mspx#EOE

Sounds like you've got something seriously wrong there - I've never seen any sign of this with either the Windows client (XP or Vista) or the vanilla ISC NTP software. What sort of Internet connection do you have?

Thanks for the link. Using it, I set my laptop to sync once daily.

Anyway.. I have a fast cable connection. This is the exact error:

Please test Your local time server (pfsense) from windows machine. Is it synchronized to upstream servers at all? Stop windows time service, install ntpdate, and do test:

ntpdate -d yourlocalpfsenseserver

I think - better way for company's local time source - to use BSD "stock" ntpd from www.ntp.org, not OpenNTPD. Configure 3-5 reliable stratum1 or stratum2 time servers and keep Your windows machines always happy.
