Windows 2003 Domain Controller Won't Sync Time w/ External Clock

[Guest Marks70]

I have a very small domain consisting of one domain controller and a member

server. I've tried configuring the DC to synchronize its clock with an

external source following MS article: How to configure an authoritative time

server in Windows Server 2003 (816042). My DC does have the PDC operations

role assigned to it. However, I keep getting the following errors logged in

my System Event Log:

 

Source: W32Time

Event ID: 38

The time provider NtpClient cannot reach or is currently receiving invalid

time data from time.nist.gov (ntp.m|0x8|192.168.99.28:123->192.43.244.18:123).

 

Source: W32Time

Event ID: 47

Time Provider NtpClient: No valid response has been received from manually

configured peer time.nist.gov,0x8 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.

 

Source: W32Time

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 15 minutes. NtpClient has no

source of accurate time.

 

I then performed the "fix" from this Microsoft article since it described

the symptoms I was experiencing: Time synchronization may not succeed when

you try to synchronize with a non-Windows NTP server in Windows Server 2003

(875424). Unfortunately, this didn't solve the problem.

 

Any ideas on how to fix this?

 

Thanks. Here are my registry entries for the Windows Time Key:
