    Can't synchronise with time server


    I can't synchronise Windows (version 2004) with any time server.

    I noticed this particularly last night after I had done a repair and therefore had taken out the battery for a while, but I think it may have been going on for much longer than that because I vaguely remember thinking I had sorted out a similar problem months ago, although I now doubt whether the problem had really been resolved.

    One particularly confusing thing is that when I try to sync through the control panel, it tells me that my last successful sync was whatever my last unsuccessful sync was, making me think that the problem has been resolved when it hasn't. In fact a posted here about this problem early this morning, but I marked the post as solved because of this misleading message. Date & Time settings give me an earlier, also fictitious time for my last successful sync.

    I have tried restarting the Windows Time server. I have tried rebooting. I have tried using three different time servers (time.windows.com, pool.ntp.org and time.nist.govt), but Windows won't sync with any of them. How can I fix this?

    How far is the time from the correct time? By design Windows will not sync with a time server that is to different from the current time. I don't know what the limits are but with several hours or more it will fail.

    Unrestricted time sync has security implications on large networks.

    Less than 2 minutes.

    You might find it useful to check you have followed the procedure in
    Synchronize Clock with an Internet Time Server - TenForumsTutorials
    and then to post a link in there to draw attention to this thread.

    When you use Option 2
    - in an elevated command window
    Code:
    w32tm /resync
    do post back here if you get any errors that the tutorial does not address.

    Do you use any third party firewall or VPN that could be blocking something related to time sync?

    Confirming time sync works on another PC you have connected via the same router will give you some assurance that it's not your router and you're testing correctly if that helps.

    Something interesting and confusing happened when I tried your suggestion. First of all, I tried to synchronise on another computer on my home network (which is configured to use time.ntp.org) and it didn't work. Then I went back to my laptop and tried again (using time.nist.org) and, as before, sync didn't work. So then I turned on the VPN (NordVPN) and tried, and it synced successfully after perhaps 2 to 4 seconds. And then I turned off the VPN, putting things back to how they were the last time sync didn't work, and this time it successfully synced a second time, again after something like 2 to 4 seconds.

    And I should add (because I forgot about it when I wrote the OP above) that at one point yesterday I did manage to get one successful sync, which seemed to be connected with manually changing the time, but I haven't been able to repeat this.

    More testing required I suppose, but now you're onto it

    If you set the time to an incorrect value, then reboot and check the time, what happens? Seems like a good test to run.

    Another place to look for clues: Event Viewer -> Windows Logs -> System -> Filter Current Log (right-side), Event sources: Time-Service

    I'm not the OP, but I just tried the Option 2 suggestion, but I got an error message:

    The following error occurred: The service has not been started. (0x80070426)
    So maybe the OP also has this issue. I haven't had the time yet to read the tut.

    Yes, that error is indeed dealt with in the tutorial.

    When seeing time issues I first check that the BIOS is correct then in the OS I go to WorldTimeServer.com: Current Local Time and Date in any Zone and verify. NIST/National Institute of Standards and Testing is good but sometimes I need to see what different locations have and in particular those that have a half-hour difference.
