Which internet time server do you use in your Windows Server 2003 time
source? I've been having problem sync'ing with the following time source:

time-a.timefreq.bldrdoc.gov
time-b.timefreq.bldrdoc.gov

The following events have been logged during the past few days:

Event Type: Error
Event Source: W32Time
Event Category: None
Event ID: 29
Description:
The time provider NtpClient is configured to acquire time from one or more
time sources, however none of the sources are currently accessible. No
attempt to contact a source will be made for 30 minutes. NtpClient has no
source of accurate time.

Event Type: Warning
Event Source: W32Time
Event Category: None
Event ID: 47
Description:
Time Provider NtpClient: No valid response has been received from manually
configured peer time-a.timefreq.bldrdoc.gov after 8 attempts to contact it.
This peer will be discarded as a time source and NtpClient will attempt to
discover a new peer with this DNS name.

I ping them and they reply just fine (under 50 ms). Is time.windows.com a
reliable source?

Thanks in advance.
 
Re: Time Server

Typically, I use the US Naval Time Servers... you will only need to select
one of the three as they are load-balanced:

# ntp2.usno.navy.mil
Location: Time Service Dept., U.S. Naval Observatory, Washington, DC
Synchronization: NTP V4 primary (USNO Master Clock H-masers plus GPS)
Access Policy: open access for MIL, GOV, and other stratum 2 servers. Choose
only one of tick/tock/ntp2.usno.navy.mil.

# tock.usno.navy.mil
Location: Time Service Dept., U.S. Naval Observatory, Washington, DC
Synchronization: NTP V4 primary (USNO Master Clock H-masers)
Access Policy: open access for MIL, GOV, and other stratum 2 servers. Choose
only one of tick/tock/ntp2.usno.navy.mil.

# tick.usno.navy.mil
Location: Time Service Dept., U.S. Naval Observatory, Washington, DC
Synchronization: NTP V4 primary (USNO Master Clock H-masers)
Access Policy: open access for MIL, GOV, and other stratum 2 servers. Choose
only one of tick/tock/ntp2.usno.navy.mil.

Re: Time Server

I changed it to tick.usno.navy.mil and restart w32time service. Looks like
it's sync'ing now.

Event logs:
The time service is now synchronizing the system time with the time source
tick.usno.navy.mil
The time provider NtpClient is currently receiving valid time data from
tick.usno.navy.mil

Thanks much.

Re: Time Server

Hello John" a,

Have a look here about time servers:
http://www.pool.ntp.org/

Make sure port 123 is open on your firewall, if used.

Best regards
