Windows 2003 W32Time errors

We have two W2K3 Forest root PDC emulator servers that are set to be the time servers for our company. One is our main W2K3 AD server for our internal network our other is on our DMZ which hosts our web site servers. Both systems are configured to be the primary time server NTP hosts. However both systems receive the following event errors so neither is able to sync with external NTP sources.

Event ID: 29

The time provider NtpClient is configured to acquire
time from one or more time sources, however none of
the sources are currently accessible.  No attempt to
contact a source will be made for 60 minutes.
NtpClient has no source of accurate time.


Event ID: 47

Time Provider NtpClient: No valid response has been
received from  manually configured peer time.windows.com
after 8 attempts to contact it. This peer will be discarded
as a time source and NtpClient will attempt to discover
a new peer  with this DNS name.  

Event ID: 38

The time provider NtpClient cannot reach or is currently
receiving invalid time data from
time.windows.com (ntp.m|0x0|172.16.38.171:123->207.46.130.100:123).

We have put on a packet tracer and see that it is able to reach the destination NTP server but it does not receive a reply packet. We installed a freeware NTP utility called about time and put it on both systems and it successfully reached and synced the time fine but it we would like to be able to utilize the built in time service. I have seen multiple questions on different NG's on this issue but none seem to answer our problem. Please Help!

Easiest fix I know is to:

1) make absolutely certain that your firewall is configured to pass the NTP packets in both directions

2) install TARDIS 2000.  Tardis 2000 installs either as a program that runs 'interactive' or as a service on win2k.  I run mine interactive on my machine, but that's because it's always logged in...  anyway, you can then use TARDIS on the installed machine to be the NTP server for the entire network.

Thank you for your reply John.

     I already know that I can patch it by using another applicaiton but I posted hear to see if I can find out how to fix it. I am fully sure that it is not a firewall isssue, as I had stated that I tested another third party applicaiton that was able to use port 123 and sync the time with no problems. If anyone else can offer any help I would greatly appreciate it.

W32 time is a modified version of NNTP.  I tried myself to get it to work for weeks on my Win2k server and found that external servers would not respond to query.  On the other hand, if I set the PC's to synch off of the server they always would... the problem was establishing the synch on the master, as it were.  Seems that w32time devices like to talk only to eachother...

So, I put Tardis on the master and my network of computers is now completely and totally in synch.  By the way, Tardis is 'fully enabled' shareware.  You only pay if it works for you.  No reg-code needed or anything like that.
