  1. There are enough new people here that I feel I should post this again.

    I found this reply I wrote to a question on 10/28/2001. It is still
    applicable to, and
    works just fine with Vista. I have added what additional may help with

    "Windows XP, as loaded, automatically updates the system time every 7 days
    from one of two time servers (more choices available in Vista). This
    interval can be changed as follows:

    Go to Start. Type run in the search box (new for Vista).

    In the search box type regedit.

    Using regedit, search (press ctrl/F) for "specialpollinterval" without the

    Double click on the key in the right screen.

    Click on decimal.

    You will see that the decimal value is 604800, the number of seconds in 7

    Highlight the number to edit this decimal value to any value you desire,
    remembering that there are
    86400 seconds in one day, 3600 seconds in an hour.

    Click OK

    Press F3 to find the next instance of the same key

    Do the above for each instance of the value "specialpollinterval".

    When you get to the end of the registry, close the window.

    Reboot system.

    You have now changed the polling interval of when your computer will update
    it's internal clock with that of the internet time server.
