Hello,

I am using a System based on FreeBSD 6.3.
On this System an automatically generated ntpd.conf file is generated in
order to synchronize the System clock with a NTP Server. I want to use a
Windows 2003 or 2008 Server to act as the NTP Server. On the Windows System
the NTP Server (Windows Time Service) is *correctly* running. The thing is
that even if there are NTP traffic between the client and the Server (NTP
Client and Server IP packet), My FreeBSD is not synchronizing at all:

freebsd-client>ntpq -p 127.0.0.1
     remote           refid      st t when poll reach   delay   offset
jitter
=======================================================
 NTP_server      192.168.10.6     2 u  103 1024    1    1.037  -587367
0.002


As you can see the offset is huge and never decreases as in a normal way...

My ntpd.conf file looks like:
-----------
# File is automatically generated
# Do not edit
tinker panic 1
tinker step  1

# ntp servers list
server 172.30.1.5

# files informations
driftfile       /etc/ntp.drift

# restriction informations
restrict default ignore  # do not allow request by default
restrict 127.0.0.1       # allow localhost for debugging
restrict 172.30.1.5     nomodify
------------

my ntp.drift file
------------
-101.101
------------

I know that maybe the Microsoft NTP/SNTP implementation is not
RFC-compliant, but is there a way to configure my NTP client in a more
"compatible" (less strict) way to adjust its time with a Windows Server?

Thanks
