SubscribeMcAfee Firewall Blocks Internet Time Synchronization
Posted on Nov 26, 2007 under Software Tips |If your computer is not synchronizing with your internet time server and you are running McAfee Firewall, it may be blocking access. Port 123 must be open for your computer to be able to synchronize time.
To unblock it, you can access the setting by going into McAfee Security Center
Click Configure > Internet & Firewall > Firewall Protection > Advanced > System Services > Network Time Protocol Port 123 and change the setting.

Thanks so much! This helped me to fix the problem that I noticed just today. I wonder why McAfee decided to block that. I am sure that the sync had worked some time ago. (McAfee firewall came directly with the computer)

I tried this along with everything else I could think of and still can’t update!
Even if I turn off all firewall protections I get the same error message!!
