I recently bought a new PC that runs Windows Vista. One thing I noticed is that Vista has the ability to automatically sync it’s system clock through time server on the Internet. Since the system clocks on PCs are horrible at maintaining accurate time, this is a great feature. However, the feature kept giving me connection errors.
After a quick Google search, I figured out the problem. McAfee SecurityCenter (came preinstalled on my PC) is set to block the default time server port (port #123). I configured SecurityCenter to allow traffic on that port and now time synch works. Thanks to a comment by “Mr B” to an article at ITsVista for helping me figure this out.
I also updated my registry to add a few other time servers. Thanks to the Tech Support Guy discussion forums for that info.
