Error getting samples from external NTP source
- From: Sergio Arzenton <Sergio Arzenton@xxxxxxxxxxxxxxxxxxxxxxxxx>

In a network with 6 WS2K3 Enterprise DCs (single domain/forest) I configured
one of them (the Operations Master) as an NTP client for an external reliable
NTP reference (a radio clock). The W32Time log file (with EventLogFlags=3)
reports that the WinServer2003 reaches the external NTP, gets an NTP packet
response but then ignores it. The error messages logged are: "Packet test 2
failed (response does not match request)" and then "Ignoring packet invalid
mode combination (in:2 out:4)".
I tried either setting NtpServer Type as "NTP" or "AllSync". The above
occurs in "AllSync" mode ("NTP" was even worse).
What that error message mean ? Where I could find some documentation or tip ?
(KB was unuseful).
Here follows the exact log trace. 10.1.2.1 is the reliable NTP source.
Thanks in advance for any help.
