Can't get 2003 server to sync with external time server

Posted on 2011-10-12

I have a 2003 server that is currently the PDC in a network, so all of the clients pull their time from it.  Problem is, the server's clock falls behind about a minute a day - right now, it's six minutes behind.  I tried to configure GPO to use Microsoft's time server to update the time, but the server's clock is still behind.  I tried modifying the registry (per Microsoft KB 816042) to get the server to use an external time source, but the time still lagged behind.  Finally, I tried running "net time /" and restarting the time service, but the time is still behind.  Does anyone have any possible solutions to this problem?

Thanks in advance!

    Make sure the server does not already sync it's time somehow with maybe another clock that is off.
    This can be the case if the server is a VM and has VM tools installed that sync time with the host or something like that.

    Or maybe w32tm does help you.

    Found the problem - the firewall was blocking NTP transmissions.  Since I have allowed that through the firewall, I have no problems setting my clocks with an external time server.

    Found the solution myself combing through the firewall config one day.
