I just built a new box with Vista ultimate x64. I enabled remote access and
I can see the other PCs on the network from the new Vista and can see the new
Vista from my other Vista Ultimate PC running Vista Ultimate x86.

The new box has not yet had a CD Key entered and has not yet been activated
- though I have the license to install once I am sure everything is working
ok.

When I try to use Remote Desktop from my older Vista PC to connect to the
brand new one, I get the following error:

"The authentication certificate received from the remote computer has
expired or is not valid."

Any ideas what is wrong?

Thanks,


Dale

Hello,

what's the time on your PCs? It could be that the difference of your Vista's
computers is too large. Try synchonizing it by internet.

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?

Yes...

You can increase or decrease the frequency of updates by making a simple
registry change. Add or change the "SpecialPollInterval" DWORD setting. Note
the value is in seconds...

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\W32Time\TimeProviders\NtpClient\

For example the value is set to 3600 on my Vista and XP machines (that's in
seconds), so the machines poll the time server once each hour.

Public time servers...
