Internet Time not working

Posted on 2007-10-03

Hello experts, some days ago all my systems started to fail on time sync over the internet.

Tried on different networks, so it isn't access problem.

I have these providers on my list but none works:

I get this at system log at system startup:
Time Provider NtpClient: An error occurred during DNS lookup of the manually configured peer ',0x1'. NtpClient will try the DNS lookup again in 15 minutes. The error was: A socket operation was attempted to an unreachable host. (0x80072751)
Then this one:
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 14 minutes. NtpClient has no source of accurate time.

Any idea?

Thanks in advance.

    From command line try this:

    w32tm /config /syncfromflags:manual /manualpeerlist:,,,,
    w32tm /config /update

    These IP Add. are some of your preferred NTP Servers.

    If you do an nslookup for the servers what do you get back?

    So, is the problem at DNS? Or those servers went down?

    My DNS is reverse recognizing them as:    can't find Non-existent domain    (lol)

    Well, it's working now at
