Then you check the appropriate checkbox (2nd from the top, I have a Danish version and prefer not to translate :o). That worked for me. I had the same probem with the XP firewall

Opening the Firewall settings you go to Advanced, then ICMP and Settings. Then you check the appropriate checkbox (2nd from the top, I have a Danish version and prefer not to translate :o).

That worked for me.

I'm using the free McAfee software that comes with Comcast. This has been bothering me for years. Yes, McAfee should have the default set to ON. James Murray -- you should consider putting a Note about this fix at the top of your page. I almost didn't read down this far. (esp. since Vista is more prevalent, and NTP isn't as likely to be the cause). Thanks, Nick — It was McAfee. I’m using the free McAfee software that comes with Comcast.

My only guess is that the Windows network time service wasn't running on that computer when McAfee firewall was installed, therefore it left the port closed. However, when the service was later started, the McAfee firewall should have popped-up a box indicating that the was trying to connect to the specified network time server. I would suggest sending an email to McAfee's tech support describing this problem and solution and let us know what they say about it.

Im 99% sure the problem is with McAfee firewall, HERE is how you fix it quickly and easily: For anyone else pulling their hair out, open McAfee. Go to the Advanced menu if you aren’t already there. Click on the Configure box. On the left, click on Internet & Network. Now click the second grey row that says Firewall protection is enabled. Click Advanced… On the left, click System Services. Check the box next to Network Time Protocol Port 123. Click Apply, then OK. Then follow the synchronization steps as usual (only it’s best to enter another website than the junk ones they have listed). This worked! THANK God!

Wireshark verifies this. time-b.nist.gov - Through wireshark it is NTP (port 123) and it responds however XP Time/Date page still shows an error that it is receiving duplicate packets. Wireshark verifies this. There is an issue and I have not found any help in TechNet about this. Any ideas? Also, be advised, that having your time correct is very, very important if you are using site-to-site VPN or client-to-site VPN. In the later case you must point your laptop users to a public NTP server otherwise they cannot verify NTP before connecting to the VPN and, if they are even a minute off, they may not connect properly or at all. Looks like there is a problem with all of the listed sites:

time.nist.gov
time-a.nist.gov
time-b.nist.gov

time.nist.gov - Through wireshark it is NTP (port 123) and it responds however XP Time/Date page still shows an error.

I, too have my home PC set to acquire the time automatically. I haven't checked it in awhile, so if it's off, I will definately be paying Regedit a visit! Thanks! Excellent article, Mr. Murray.
