Thanks for the tip. That was exactly the problem. I have gotten in the
habit of not considering time on a new PC because Windows handles it on its
own. But this was partly my fault; apparently when I set the time and date
in the BIOS when I built the machine, I set it one day off.

What was weird is that I discovered, after posting the original question
here, that I could access the new box if I turned its Vista firewall off so I
thought I had a firewall issue. But after reading your suggestion and fixing
the time difference, I was able to access the new box with the firewall on.

One thing I discovered while fixing the time is that Vista defaults to
updating the time from the Internet only once a week. Is there a way to
change that?
