Unable to update root certificates from MS
Hi there. A few Windows 7 computers are not updating their root certificates as evidenced by the fact that some websites report having a bad certificate, while that same website is fine from a computer not affected by the issue. The common thread on all of these computers is the "A certificate chain could not be built to a trusted root authority" event logged repeatedly in the event log. A google search yielded a lot of results, but they all seem to be pertaining to someone who wants to import their own CA and is having trouble doing that because of some issue that's easily solved. None seem to pertain to what I'm trying to do. Anyone have some insight into this?

Hi, Thanks for posting in Microsoft TechNet forums. According to my understanding, on some of your Windows 7 workstations, Trusted Root CA certificates do not appear to be downloading and installing from Windows Update correctly, and received the Event ID 4110 in the Event Viewer log. What’s your server? Have you automatically update the root certificates?

It works again after Microsoft distributed the new CTL on March 3rd-4th. http://social.technet.microsoft.com/wiki/contents/articles/troubleshoot-root-certificate-update-failure-march-3-2011.aspx?wa=wsignin1.0
