I'm embarrassed to write this but will do so because it may help someone else in a bonehead situation.
This is a new machine with a newly installed OS, and the date and time were set incorrectly.
As soon as I set the correct D&T, problem solved.
Thanks for the responses.
I have noticed now in Windoze that if your date and time are out of a range Windows will not update it. Which is really annoying.
I would like to have it updated regardless. Some of my machines may not run for a while or the CMOS will reset because of a low battery or whatever.
Good catch though.
